Flow Sensors & Flow Indicators

Combines high-visibility rotors with solid-state Hall Effect electronics in a compact panel-mounting housing. Output pulses at the same voltage as the input (4.5–24 VDC) with frequency proportional to flow. Ideal for water purification, dispensing systems and cooling loops. Potable water (RFO-PW) version available.

Simple, direct and reliable visual flow indicator — no electronics required. Flow rate is estimated or confirmed by viewing the speed of the turning high-visibility rotor. Either port may be used for incoming flow and the bayonet-mount lens is easily removed for maintenance or cleaning. Ideal where a low-cost, no-power flow check is needed.

Combines high-visibility rotors with solid-state electronics for accurate flow rate output via a 0–10 VDC analog signal with integral visual confirmation. The RFA conditions the pulsed Hall Effect output to a smooth analog voltage proportional to flow rate — ideal for PLC and data acquisition systems requiring continuous flow rate monitoring.

Combines visual confirmation of flow with dynamic 1-amp electronic switch operation. The RFS triggers a switched output when flow drops below or exceeds a set threshold — ideal for semiconductor processing, lasers, medical equipment, X-ray machines and cooling systems requiring flow/no-flow protection.

The XFT is a non-invasive clamp-on ultrasonic flow meter — no pipe cutting, no process shutdown and no risk of contamination. Simply clamp onto the outside of the pipe. Features a full-colour rotatable LCD display, MODBUS® RTU communication and analog outputs. Suitable for pipe sizes 3/8" to 1.5" (16 to 52 mm OD). Compatible with stainless steel, PVC and PPR pipe materials. Ideal for chiller systems, data centre cooling, water/wastewater and semiconductor applications.

Hall Effect turbine flow sensor ideal for OEM applications involving low-flow liquid monitoring. Mounts in any orientation and is not influenced by changes in system pressure caused by ageing filters — unlike timing-based systems. Low cost with ½% repeatability makes it an ideal replacement for dispensing timer systems. Available in Nylon 12 (up to 200 psig) and brass body (up to 350 psig) versions. Each sensor is 100% tested for years of reliable service.

Proven turbine technology in an ultra-compact package for very low-flow applications. The lightweight turbine reacts quickly to on/off dispensing applications — highly repeatable and ideal for volume dispensing and flow rate measurement. Nylon 12 body compatible with water, coolants and many chemicals. NPN sinking open collector output. Each unit 100% tested for reliable long-term service.
