Flow sensor

Ultrasonic oxygen sensors measure oxygen concentration and flow by detecting ultrasonic time-of-flight changes in gas. Learn how US1001 and US1010 support oxygen concentrators, oxygen chambers, and medical oxygen monitoring with fast response, high accuracy, wide voltage input, and flexible integration.

Volume flow readings can drift 10–20% without pressure/temperature compensation. Learn how thermal mass flow sensors measure true mass flow with low pressure loss, strong low-flow response, and high accuracy—plus how to select the right range, gas type, stability, and outputs.

Winsen’s new FRn series MEMS thermal mass flow sensors deliver low start-up flow, excellent zero/full-scale stability, and fast response for micro-flow gas process control. Available with I²C and 0.5–4.5V analog outputs.

An ultrasonic flow meter is a device used to measure the flow rate of a fluid by utilizing ultrasonic waves.Ultrasonic flow meters are non-intrusive, meaning they do not require direct contact with the fluid. They are commonly used for measuring the flow of liquids, such as water, chemicals, and oils, as well as gases, in various industries including water treatment, oil and gas, HVAC, and industrial processes.
