Gill Sensors & Controls: Advanced Solutions for Measurement & Control

Ultrasonic Flow Sensors

Solid-state ultrasonic flow sensors for liquids and gases

About our Flow Sensors

Utilising over 20 years of experience in design and development of ultrasonic flow sensing technology, we produce bespoke, high-accuracy flow sensors for liquids and gases.

The flow sensor technology uses the ultrasonic 'time of flight' principle to determine flow rate, with minimal intrusion into the flow path. With no moving parts, the flow sensors give excellent long-term reliability unmatched by mechanical paddlewheel, impeller and hot wire flow sensors.

The majority of our flow sensors are custom designed for the application in which they will be used. Our design teams are often able to utilise existing electronic assemblies, packaged in a bespoke sensor housing. This not only significantly shortens the lead time to delivery but also reduces sensor development cost.
