Magnetostrictive Level Transmitter

Physical properties of certain materials can be applied using ingenuity and creativity to create useful appliances. Magnetostriction, a physical property of ferromagnetic materials, produces a change in shape or dimension in the subject material when it is magnetized. This basic principle is integrated into a liquid level transmitter by extending a sensing wire along the interior length of a tube immersed in a process tank or other vessel containing the liquid to be measured. The transmitter pulses the sensing wire with an electrical current, creating an electromagnetic field. A magnetic float, travelling along the outside of the sensing tube, rises and falls as the liquid level in the tank changes. As the float moves along the length of the sensing tube, it creates a torsional stress in the sensing wire, starting at the position of the float, which matches the level of liquid in the tank. A sensing element converts the torsional stress in the wire to an electrical pulse. The transmitter measures the time differential between the initial pulse it sent down the sensor wire and the pulse resulting from the torsional stress and then calculates the position of the float and the liquid level.

These devices are very accurate and operate on a standard 2-wire loop. There are numerous options and variants that allow configuration for each application.

Direct Reading Level Indicator Gauge for Process Tanks

tank liquid level

Anytime there is a process tank, there is a need to know how full it may be. There are numerous methods and technologies that can be applied, with varying levels of complexity and accuracy, to provide a measure and indication of tank liquid level.

A direct reading tank level gauge is essentially an extension of the tank that provides a visible indication of liquid level. The level is not inferred from a pressure reading or tank weight, nor is it represented by the movement of a float or other device. The actual process liquid can be seen by an operator or technician by looking at the clear display area of the gauge.

A direct reading level gauge connects to tank fittings at significantly high and low points along the tank side wall. The connections permit process liquid to flow into the gauge, with the level in the gauge being the same as that in the tank. A scale on the gauge provides a reference point for liquid level that can be recorded or used in other ways in the process. The simple device has no moving parts, requires no calibration, demands little to no maintenance. It can be the primary level indicating device for a manually operated fill, or act as a backup or local indicator for an automated process.

There are pressure limitations for these indicators. Higher pressure applications, or those with liquids that may foul the clear viewing area of the indicator are better handled with a magnetic level indicator. Like all instruments, proper application is the key to getting the best performance.

Magnetostrictive Level Transmitter

The numerous level control technologies, methods, and instruments all have an application range or niche where they provide a feature set and performance advantageous to other measurement means. The particular set of attributes that can push one instrument over the top in the selection process is specific to each user and application.

Magnetostrictive level transmitters provide a continuous signal indicating liquid level in a vessel. They should not be confused with what are called magnetic level gauges, an instrument that locally provides a visual indication of liquid level.

Magnetostrictive level measurement employs a precise measuring of the transit time for an electric pulse travelling on a wire extending down an enclosed tube oriented vertically in the subject media. A magnetized float on the exterior of the tube moves with the liquid surface. The float’s magnetic field interacts with a magnetic field produced along the wire to generate a return signal to the transmitter head. Processing the time from emission to return provides a measure of distance to the liquid surface.

These level transmitters offer good accuracy and ease of installation and maintenance. They are best applied with relatively clean fluids. Media that will impede the free movement of the float along the sensing tube should be avoided. Magnetostrictive level instruments are often employed alongside, or integrated with, a magnetic level gauge. The magnetic gauge provides a local indication of tank level, while the magnetostrictive transmitter delivers a level signal to monitoring and control equipment.

Magnetostrictive Level Transmitter Retrofit to Magnetic Level Gauge

with a magnetostrictive transmitter to
provide a continuous process level signal
Jogler
A magnetic liquid level indicator provides a reliable and highly visible reading of its indirect level measurement in tanks and vessels. While useful for local visual indication of tank level, the instrument does not provide an electrical signal output that can be utilized for process control or other monitoring functions. Several magnetic level gauge manufacturers offer combination units that incorporate another measurement technology to provide an analog signal corresponding to liquid level.
What if your installation has an existing magnetic level indicator and you need an analog level signal?
One manufacturer, Jogler, offers a magnetostrictive level measurement instrument that can be retrofitted to an existing magnetic level gauge, even those from other manufacturers. The low profile waveguide mounts slightly away from the existing magnetic level unit to isolate it from temperature and vibration. It is specifically designed for use with an existing magnetic level indicator and provides an analog output signal that is accurate, stable, and responsive.

A magnetostrictive level measurement instrument employs a magnetic float that moves along a sensing wire as the tank level changes. Fixed interval current pulses are sent down the wire, with the resulting electromagnetic field being interrupted by the magnetized float. This interruption causes magnetostriction in the sensing wire, which is manifested as a torsional stress wave along the wire. A piezoceramic sensing element converts the torsional stress into an electrical signal and the transmitter produces an output signal based upon the time interval between the initial pulse and the return pulse produced as a function of the float position.

There is more to be learned, so share your liquid level measurement requirements and challenges with instrumentation specialists. The combination of your process knowledge and their product application expertise will produce effective solutions.

Specific Gravity Analyzer for Fluid Process Applications

Speicifc Gravity Analyzer
Jogler 
Specific gravity is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume (Thank you, Wikipedia).  Often the reference substance for liquids is pure water at a temperature of +4°C, which is assigned a value of 1.0. The specific gravity measurement is used throughout many industries as a measure of concentration in a solution. An example would be the concentration of sugar in a solution of water and sugar. 

For purposes of process analysis, an instrument providing continuous measurement is generally advantageous since its operation accommodates the changing nature of the process. One device employs two tubes and a calibrated float to provide a continuous display of a liquid's specific gravity. Liquid from the process fluid sample line enters the bottom of the inner tube containing the float. A very small sample flow rate is needed. The float is calibrated for the subject process liquid and has a reference scale from which the specific gravity is manually read. The sample fluid overflows the inner tube, collecting in the outer tube where it is drained away. The continuous, though small, flow of sample liquid enables each reading to reflect the current process condition.

This simple and effective instrument provides accurate measurement and requires little maintenance. Share all your process fluid analysis challenges with application specialists. Combine your process knowledge with their product application expertise to develop the most effective solutions.

Fluid process control operations often involve vessel or tank storage of liquids. Continuous and accurate indication of the liquid level within the tank is an essential data point for process control decision making and safety. Several methods and instrument types are available for tank level measurement, each with its own set of attributes that may be advantageous for a particular installation. Selection criteria for a tank liquid level indicator may include:
  • Direct or indirect measurement of level
  • Level measurement accuracy and reliability
  • Tank shape, regular or irregular
  • Media compatibility with measurement device
  • Requirements for maintenance or calibration
  • Compatibility with process temperature and pressure range
  • Local display and visibility
  • Level indication signal type and transmission
  • Level alarm switches or other indicators
The selection of a magnetic level indicator, also referred to as a magnetic level gauge, for the project will likely be based upon at least one of the instrument's strengths. Magnetic level gauges have a host of potentially positive features for level indication.
  • Continuous level measurement
  • Operable without electric power
  • Direct visual tank fluid level indication, regardless of tank shape or profile.
  • Wide range of operating temperature and pressure
  • Breakage resistant construction
  • Range of construction materials available to accommodate corrosive media
  • Measuring indicators, switches, and transmitters mounted externally, without contacting the medium being measured.
  • Low maintenance operation.
  • Readable level indication from greater distance than glass sight gauges.
  • Applicable to large fluid level ranges with a single instrument.
Magnetic level indicators have a strong position in the tank liquid level measurement field and should be considered as a candidate for fulfilling those application requirements. There are many options available to customize the level indicator for each specific application. I have included a technical data sheet from Jogler, a manufacturer of level instrumentation, for more detail. Share your application challenges with a sales engineer that specializes in level measurement. Combining your process knowledge with their product application expertise will yield positive solutions.

Magnetic level gauges isolate of the process inside of a sealed piping column, thus eliminating the possibility of leaking seals and cloudy or broken site glass. Magnetic level gauges (gages) allow for easy cleaning access and a wide variety of mounting styles and process connections. They also provide improved visibility with highly visible flippers.

Magnetic level gauges are designed with a float in a sealed tube, embedded with permanent magnets. As process level changes, the float rises and falls, and the magnets in the float couple with an external indicator. The indicator is completely isolated from the process.

The following video provides a brief overview of Jogler level products. Jogger is a Baton Rouge, Louisiana manufacturer of high quality magnetic level gauges, magnetostrictive transmitters, direct-reading level gauges with armored shield, sight flow indicators, specific gravity analyzers, point level switches and other accessories. Jogler products are custom designed to meet customer specifications and manufactured to applicable ASME B31.1 and B31.3 code requirements to ensure reliable operation and maintenance free design.
