What Are Direct-reading Level Gauges, Site Flow Indicators, and Specific Gravity Analyzers?

Direct-reading Level Gauges (Jogler)

Direct-reading Level Gauges

Direct-reading Level Gauges are the simplest, most reliable way to determine the level of liquid in a tank or vessel because they give you a direct view without compromising the integrity of your process system. Direct-Reading level gauges are installed so that the liquid level in the transparent sight tube is always the same as the liquid level inside the tank or vessel.

Sight Flow Indicators

Sight Flow Indicators (Jogler)

Sight Flow Indicators are the simplest, most reliable way to observe liquid or solids flow without compromising the integrity of your piping system. They are available in either armored styles for protection in exposed locations, or lantern styles for 360-degree viewing.

Specific Gravity Analyzers (SGAs)

Specific Gravity Analyzer (Jogler)

Specific Gravity Analyzers (SGAs) are a dependable and accurate method for measuring and sampling process liquid levels in virtually any application:

• Acids
• Caustics
• Co-generation
• Light Hydrocarbons
• Beverages, etc.

SGAs present accurate visual verification of liquid density, can be cross-checked against temperature and are compatible with most requirements. Also, they require only small amounts of product for specific gravity measurement.

Laser Level Transmitter Technology

accurate, and easy to use.

Jogler, manufacturer of level measurement instruments, provides a laser level transmitter for industrial process measurement and control applications. The rugged instrument provides continuous non-contact level measurement for process automation and inventory management across an array of industrial applications.

A laser level transmitter can provide reliable measurement of solids or opaque liquids with little interference from granular or foaming surfaces. The technology provides for very long measuring distance, enabling a large standoff from a hazardous location or measuring within a very large vessel. The narrow beam emitted by the transmitter can be easily located to avoid false readings from mixers or other purposeful obstructions within a vessel. The long measuring range, narrow beam, easy installation and high accuracy make the laser based level measurement technology suitable for application in silos, tanks, hoppers, chutes, and bunkers. In addition to being a non-contact measuring method, a laser level transmitter can function effectively through a transparent sight glass installed on a vessel. The complete isolation of the instrument from the process media can be beneficial in many applications.

Liquid Level Measurement Using Hydrostatic Pressure

Hydrostatic pressure can be used to measure liquid level
in tanks or other vessels.

Pressure measurement is an inferential way to determine the height of a column of liquid in a vessel in process control. The vertical height of the fluid is directly proportional to the pressure at the bottom of the column, meaning the amount of pressure at the bottom of the column, due to gravity, relies on a constant to indicate a measurement. Regardless of whether the vessel is shaped like a funnel, a tube, a rectangle, or a concave polygon, the relationship between the height of the column and the accumulated fluid pressure is constant. Weight density depends on the liquid being measured, but the same method is used to determine the pressure.

A common method for measuring hydrostatic pressure is a simple gauge. The gauge is installed at the bottom of a vessel containing a column of liquid and returns a measurement in force per unit area units, such as PSI. Gauges can also be calibrated to return measurement in units representing the height of liquid since the linear relationship between the liquid height and the pressure. The particular density of a liquid allows for a calculation of specific gravity, which expresses how dense the liquid is when compared to water. Calculating the level or depth of a column of milk in a food and beverage industry storage vessel requires the hydrostatic pressure and the density of the milk. With these values, along with some constants, the depth of the liquid can be calculated.

The liquid depth measurement can be combined with known dimensions of the holding vessel to calculate the volume of liquid in the container. One measurement is made and combined with a host of constants to determine liquid volume. The density of the liquid must be constant in order for this method to be effective. Density variation would render the hydrostatic pressure measurement unreliable, so the method is best applied to operations where the liquid density is known and constant.

Interestingly, changes in liquid density will have no effect on measurement of liquid mass as opposed to volume as long as the area of the vessel being used to store the liquid remains constant. If a liquid inside a vessel that’s partially full were to experience a temperature increase, resulting in an expansion of volume with correspondingly lower density, the transmitter will be able to still calculate the exact mass of the liquid since the increase in the physical amount of liquid is proportional to a decrease in the liquid’s density. The intersecting relationships between the process variables in hydrostatic pressure measurement demonstrate both the flexibility of process instrumentation and how consistently reliable measurements depend on a number of process related factors.

Solutions to process instrumentation and measurement challenges are most effective when developed in concert with a product application specialist. The combination of user knowledge and experience with product application expertise will lead to a successful project.

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.
