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.

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
