Flow, Level & Pressure

Icon Process Controls instruments for measuring and controlling liquids in pipes and tanks. Flow: paddle wheel, magnetic, ultrasonic and oval gear meters, plus flow switches. Level: float, tuning-fork and non-contact switches for point level, and radar, ultrasonic and submersible transmitters for continuous level. Pressure: dial gauges with gauge guards, LED gauges, switches and 4–20 mA transmitters, with pulsation dampeners for metering-pump lines. Leak detection and alarms: leak sensors, controllers, sentry alarms and Sentinel tank monitors. Display and control: ITC controllers and data loggers. Everything is quoted: send the liquid, the pipe or tank size and the output you need with a quote request.

Flow, level and pressure FAQ

Gauge, switch or transmitter?

A dial is not a signal. If a PLC, an alarm or a pump has to react, use a switch or a 4–20 mA transmitter, or an LED gauge that adds both. A 4–20 mA loop carries the reading and the power on the same two wires; see our 4–20 mA transmitter guide.

Point level or continuous level?

A point-level switch says when a liquid reaches one height, for a high alarm, a low cut-off or a pump start. A continuous transmitter reads the level across the whole range as a 4–20 mA signal. See our float switch guide.

Which wetted material?

Start with what touches the liquid: Icon's plastic gauges have PVC, PP or PVDF bodies, and float switches come in PVC, PP, PVDF or 316 stainless steel depending on model. Check the material against your chemical's SDS before you choose the range. See our pressure gauge guide.
