Ultrasonic Water Flow Meter Calibration

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.

Ultrasonic water flow meter calibration.

Regular calibration of your flow meter instruments ensure that the flow meter s measurements are as accurate as their specifications say they are. Our comprehensive flow meter calibration services can be custom tailored to meet your specific requirements either at your site or through. Ultrasonic meters are commonly used for custody transfer and fiscal oil and gas measurement. These include flow meter calibration water flow meter calibration level indicator calibration level transmitter calibration level controller calibration and flow transmitter calibration.

Doppler shift and transit time. Fuji portaflow c f sc 2. Aquarion selected an ultrasonic meter from flexim americas. Most aren t robust enough for my applications.

The ultrasonic flow meter provides numerous advantages over other types of flow measuring meters. Master meter calibration technique. The american water works association standard awwa c750 10 for clamp on ultrasonic meters requires the ultrasonic meter to have 1 percent accuracy. Flow meter calibration capabilities.

Flow meter calibration at precision calibration services. Flow meter showing ultrasonic transceiver use. The main advantage provided is ultrasonic measurements are non invasive. The flow rate measurement that occurs in an ultrasonic water meter is critical to the accuracy of the meter.

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. Transit time measures the time differential between signals sent upstream and downstream. The author of the well known book fluid flow measurement e. All water meters built upon the transit time ultrasonic principle require some kind of flow calibration.

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. At pcs we offer flow meter calibration using the well known master meter method. I have a good deal of experience with ultrasonic flow meters said schultz. There are two types of ultrasonic flow meter technologies.

The master is placed in series with the flow meter being calibrated and a series of. Product information sitrans fs ultrasonic flowmeters call it the ultrasonic advantage. The flow of fluid is measured by clamping a set of transducers on a pipe. These meter calibrations are widely appreciated for their supreme quality and they require less maintenance.
