QEM Series In-Line Ultrasonic Flow Meters Datasheet

The QEM Series in line ultrasonic flow meter has been specifically designed for applications that require excellent accuracy & reliability at an OEM price point. The compact QEM Series has no moving parts; this results in a very rugged, reliable and accurate flow meter. The small footprint, lightweight device is ideal for low viscosity liquid applications including water, water based products, oils, and its all plastic construction makes it the meter of choice for many corrosive fluids.

The QEM Series flow meter bases its operation on measuring the time difference of an ultrasonic wave traveling with and against the flowing medium. The time difference is directly proportional to the fluid’s flow rate.
