Pressure, temperature, level and flow are the four common plant measurements. Of the four, pressure is the most fundamental and common. The three remaining measurements can be inferred from pressure-flow (orifice plates, pitot tube, venturi), level (hydrostatic ‘Head’ pressure), and temperature (pressure thermometer). It can even be used to infer density (pressure for a given volume) and weight (load cells). If you cannot measure it, you cannot control it.
The ability to quickly, accurately, and reliably measure pressure is invaluable when trying to control a process.
Each of these types of transmitters measures pressure. The ow transmitter, liquid level transmitter, and pressure thermometer use the measured pressure to infer another process parameter.
Read the handbook below to garner a great understanding of industrial pressure measurement.
