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.

Total Organic Carbon, referred to as TOC, is a measurement providing one of several facets to indicate the purity of a water sample or stream. Organic contamination in water for use in power generation, semiconductor manufacturing, and pharmaceutical production poses a number of operational risks or quality failures that can substantially impact process output. The elevated presence of carbon compounds in certain purified water sources can be an indicator that water treatment processes are not performing properly and need attention.

The measurement technology involves oxidation of carbon compounds in the presence of UV light and measuring sample conductivity. Processing of the raw measurement yields a value for TOC. Analytical instruments benefit from having features and attributes that lessen the need for human involvement and deliver rapid and accurate results. Mettler Toledo provides an advanced solution for TOC measurement with it 5000TOCi analyzer.

  • Fast continuous measurement
  • Reagent and chemical free

Calibration of Process Instrumentation

Industrial temperature transmitter requires
periodic calibration to assure reliable performance

Calibration is an essential part of keeping process measurement instrumentation delivering reliable and actionable information. All instruments utilized in process control are dependent on variables which translate from input to output. Calibration ensures the instrument is properly detecting and processing the input so that the output accurately represents a process condition. Typically, calibration involves the technician simulating an environmental condition and applying it to the measurement instrument. An input with a known quantity is introduced to the instrument, at which point the technician observes how the instrument responds, comparing instrument output to the known input signal.

Even if instruments are designed to withstand harsh physical conditions and last for long periods of time, routine calibration as defined by manufacturer, industry, and operator standards is necessary to periodically validate measurement performance. Information provided by measurement instruments is used for process control and decision making, so a difference between an instrument’s output signal and the actual process condition can impact process output or facility overall performance and safety.

In all cases, the operation of a measurement instrument should be referenced, or traceable, to a universally recognized and verified measurement standard. Maintaining the reference path between a field instrument and a recognized physical standard requires careful attention to detail and uncompromising adherence to procedure.

Instrument ranging is where a certain range of simulated input conditions are applied to an instrument and verifying that the relationship between input and output stays within a specified tolerance across the entire range of input values. Calibration and ranging differ in that calibration focuses more on whether or not the instrument is sensing the input variable accurately, whereas ranging focuses more on the instrument’s input and output. The difference is important to note because re-ranging and re-calibration are distinct procedures.

In order to calibrate an instrument correctly, a reference point is necessary. In some cases, the reference point can be produced by a portable instrument, allowing in-place calibration of a transmitter or sensor. In other cases, precisely manufactured or engineered standards exist that can be used for bench calibration. Documentation of each operation, verifying that proper procedure was followed and calibration values recorded, should be maintained on file for inspection.

As measurement instruments age, they are more susceptible to declination in stability. Any time maintenance is performed, calibration should be a required step since the calibration parameters are sourced from pre-set calibration data which allows for all the instruments in a system to function as a process control unit.

Typical calibration timetables vary depending on specifics related to equipment and use. Generally, calibration is performed at predetermined time intervals, with notable changes in instrument performance also being a reliable indicator for when an instrument may need a tune-up. A typical type of recalibration regarding the use of analog and smart instruments is the zero and span adjustment, where the zero and span values define the instrument’s specific range. Accuracy at specific input value points may also be included, if deemed significant.

The management of calibration and maintenance operations for process measurement instrumentation is a significant factor in facility and process operation. It can be performed with properly trained and equipped in-house personnel, or with the engagement of subcontractors. Calibration operations can be a significant cost center, with benefits accruing from increases in efficiency gained through the use of better calibration instrumentation that reduces task time.

Measurement of pH is a common analytical operation in liquid processing. Whether chemical or wastewater operations, pH measurement provides useful information about process condition.

The sensors used for measuring pH can require care and maintenance, in the form of cleaning and calibration, to maintain peak performance. Traditionally, these operations have been performed manually by trained technicians. The task, though, is a good candidate for automation to provide cost savings and uniformity for sensor cleaning and calibration.

Mettler Toledo manufacturers four different automated cleaning and calibration systems for their analytical sensors. The offering ranges from simple water rinsing or compressed air cleaning to prevent build up to fully automated cleaning and calibration systems requiring little in the way of human intervention.

The technical data sheet below provides details about the fully automated system.

Retractable Sensor Housing for Analytical Sensors

retractable sensor housing for Mettler Toledo Thornton Ingold sensors
The retractable sensor housings are available in several configurations
Process analytical sensors generally require some "care and feeding" to maintain specified performance levels. This maintenance can require removal of the sensor from the process in which it is inserted. Clearly, it is seldom advantageous to shut down a process for maintenance when it could otherwise remain in operation. The challenge - how to service the pH, redox, conductivity, or dissolved oxygen sensors without process interruption.

Mettler Toledo, under their Ingold brand of process analytic products, provides a solution in the form of a retractable sensor housing. Models accommodate sensors for pH, redox, conductivity, and dissolved oxygen. The housings are designed to enable safe retraction of the sensor from the process, with in place sensor cleaning or further maintenance operations made simple with the process remaining in operation.
