ABB Level KM26

Overview

The KM26 Magnetic Level Gauge has provided custom engineered solutions to liquid level applications in industries such as: oil and gas, refinery, chemical, petrochemical, power generation and many more. The KM26 MLG has proven itself to be a safe, reliable, maintenance free solution for total and/or interface level detection in toxic, corrosive, high pressure and high temperature processes. Features:
  • Highly visible level indication with no process fluid in contact with the glass
  • All construction in-house by code certified welders
  • Float designed and weighted for maximum accuracy with 75 grams minimum upward buoyant force
  • Transmitter and switch options which can be installed, adjusted and maintained with no process interruption
  • Safe for corrosive, flammable, toxic, high-temperature and high-pressure applications
  • Rugged design - low or no maintenance

How do I determine which instruments I need and their cost?

This depends on what you are needing to control or measure, your operating environment, your specific process flow, and many other factors. Durkin’s process specialists can help you determine the specific process instruments (down to the part number) that suit your application, budget, and expected life-span the best. Call (314) 432-2040 or contact us.

What is process instrumentation?

Process Instrumentation are sensors and instruments used to measure and control process variables including levels, flow, pressure, temperature, pH, and humidity.

In-field instruments, such as flowmeters or temperature sensors, are close to the process or measurement point, or may even have process liquids flowing through them. Panel instruments not usually where the process is happening, but are rather located ina controlled room or with the line controls.

Common types of process instrumentation include: flow meters, rotometers, level sensors, temperature sensors, recorders (to record process data), actuators, valves, gas analyzers, positioners, and actuators.

What symbols are used for process instruments?

Depending on the program, plant standards, and engineering firm that did the drawings, symbols for process instrumentation can vary. You should have been supplied with a lead or legend sheet that defines the symbols for the particular set of drawings you are looking at. However, there are a common set of generally agreed upon symbols, examples of which you can reference here.

Robert Cook at AiCHe has put out an excellent blog post on interpreting and using instrumentation symbols. If that doesn’t help, contact Durkin and one of our team members can help you solve the mystery: (314) 432-2040

Do you only supply the brands listed?

We carry a wide-range of process instrumentation and solutions. You can see our full supplier list here, but we may be able to source brands or point you the right distributor for other brands. More importantly, we can help you determine the appropriate instrumentation and controls solutions needed to solve your process issues.
