Regular calibration of your flow meter instruments ensure that the flow meter s measurements are as accurate as their specifications say they are.
Ultrasonic water flow meter calibration.
The author of the well known book fluid flow measurement e.
The main advantage provided is ultrasonic measurements are non invasive.
There are two types of ultrasonic flow meter technologies.
The ultrasonic flow meter provides numerous advantages over other types of flow measuring meters.
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.
The american water works association standard awwa c750 10 for clamp on ultrasonic meters requires the ultrasonic meter to have 1 percent accuracy.
The master is placed in series with the flow meter being calibrated and a series of.
Our comprehensive flow meter calibration services can be custom tailored to meet your specific requirements either at your site or through.
At pcs we offer flow meter calibration using the well known master meter method.
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.

Flow meter calibration capabilities.
Flow meter calibration at precision calibration services.
The flow of fluid is measured by clamping a set of transducers on a pipe.
Doppler shift and transit time.
The flow rate measurement that occurs in an ultrasonic water meter is critical to the accuracy of the meter.
Transit time measures the time differential between signals sent upstream and downstream.
Most aren t robust enough for my applications.
All water meters built upon the transit time ultrasonic principle require some kind of flow calibration.
Product information sitrans fs ultrasonic flowmeters call it the ultrasonic advantage.
These meter calibrations are widely appreciated for their supreme quality and they require less maintenance.
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.
With the deployment of a reference standard flow measurement device the meter can be calibrated across a specific known flow range.
Ultrasonic meters are commonly used for custody transfer and fiscal oil and gas measurement.
Aquarion selected an ultrasonic meter from flexim americas.
Ultrasonic flow meters are inferential meters that uses ultrasonic technology to measure the velocity of an acoustically conductive liquid moving through it.
Tektronix provides fully accredited flow meter calibration services.
