Ultrasonic Water Flow Meter Calibration

The flow of fluid is measured by clamping a set of transducers on a pipe.

Ultrasonic water flow meter calibration.

Doppler shift and transit time. These include flow meter calibration water flow meter calibration level indicator calibration level transmitter calibration level controller calibration and flow transmitter calibration. All water meters built upon the transit time ultrasonic principle require some kind of flow calibration. Flow meter calibration at precision calibration services.

Tektronix provides fully accredited flow meter calibration services. Our comprehensive flow meter calibration services can be custom tailored to meet your specific requirements either at your site or through. Fuji portaflow c f sc 2. There are two types of ultrasonic flow meter technologies.

Flow meter calibration capabilities. I have a good deal of experience with ultrasonic flow meters said schultz. The master is placed in series with the flow meter being calibrated and a series of. The ultrasonic flow meter provides numerous advantages over other types of flow measuring meters.

Ultrasonic flow meters are inferential meters that uses ultrasonic technology to measure the velocity of an acoustically conductive liquid moving through it. They measure the velocity of a fluid in a closed pipe and utilize transducers to emit ultrasonic pulses greater than 20 khz frequency from which the flow meter can calculate the average velocity along the path of the beam of ultrasound. The main advantage provided is ultrasonic measurements are non invasive. Transit time measures the time differential between signals sent upstream and downstream.

Regular calibration of your flow meter instruments ensure that the flow meter s measurements are as accurate as their specifications say they are. The flow rate measurement that occurs in an ultrasonic water meter is critical to the accuracy of the meter. Loy upp defines calibration of an instrument or meter as the process or procedure of adjusting an instrument or a meter so that its indication or registration is in close agreement with a referenced standard this definition captures the concept of calibration as it is understood. At pcs we offer flow meter calibration using the well known master meter method.

Flow meter showing ultrasonic transceiver use. The american water works association standard awwa c750 10 for clamp on ultrasonic meters requires the ultrasonic meter to have 1 percent accuracy. Aquarion selected an ultrasonic meter from flexim americas. Master meter calibration technique.

These meter calibrations are widely appreciated for their supreme quality and they require less maintenance. Product information sitrans fs ultrasonic flowmeters call it the ultrasonic advantage. Most aren t robust enough for my applications. Because they can operate independent of conductivity viscosity temperature density or pressure sitrans fs flow sensors and transmitters deliver impressive performance for a variety of liquids and gases even under the toughest conditions.
