Call 831-244-8080 for questions

We show How the Ultrasonic Flow Meters can be "calibrated" or "linearized" to fit your specific application. This method is used when the fluid or the installation is non-ideal, such as valves, elbows, or reducing or increasing pipe sizes are used. We show using a 7 element linearizer to compensate for an exemplarily application. The units of the linearizer in m3/h to "speak" the "raw language" of the flow meter. You will want to convert YOUR flow to m3/h and then you may use any units you wish once the linearization is done, such as GPM.

These are also called Ultrasonic Transit Time flowmeters and clamp on flow meters.

These are commonly used as Ultrasonic flow meters for water and they are low cost compared to meters that require cutting into the pipe.

The MAJOR BENEFIT is you can clamp these on the outside of your existing pipe without any penetrations.

Tactical Flow Meter Ultrasonic Flow meters features LARGE LCD display, shows the Instantaneous Flow Rate, Total Flow, in user selectable units.
