Instrumentation, Measurement & Control - Palmer Wahl

Instrumentation refers to devices that measure or control physical variables such as temperature, level, flow, or pressure. These products are essential in the industry because they allow for maximum output with minimum use of raw materials. Flow instruments include flow meters, positive displacement meters, rotameters, flow switches, oval gear meters, and calibration equipment. Analytical instruments measure temperature, pH, conductivity, dissolved oxygen, turbidity, humidity, chlorine, gases, trace oxygen resistivity, and carbon. Pressure instruments include pressure gauges, pressure switches, pressure transmitters, differential pressure gauges, cryogenic gauges, O.E.M. gauges, submersible gauges, digital pressure gauges, and calibration equipment. Level instruments, such as ultrasonic sensors, magnetic float sensors, capacitance sensors, submersible pressure sensors, differential pressure sensors, float valve sensors, float switches, electro-optic sensors, and radar sensors, are used to measure the level of a substance in a container or vessel.
