General information

Besides calibration services, Badger Meter also provide you with calibrators.

Positive displacement liquid calibrators are volumetric type measurement devices, which measure the exact volume of fluid that passes through the flow meter under test  while compensating for fluid viscosity and temperature. They ensure extremely high precision fluid flow measurement.

With a repeatability of ±0,01 % of reading, the calibrators are most precise. The NIST fluid flow measurement laboratory uses this type of calibrator for their liquid flow meter calibrations requiring high accuracy. The calibrators are easy to maintain and will last 50 years or more in service. They conform to the guidelines of NIST for Round Robin Testing.

Three models can calibrate meter sizes of DN2 to DN150 at flow rates of 0,37 to 1,515 l/min. All kinds of flow meters can be calibrated: Electromagnetic flow meters, ultrasonic flow meters, turbine meters, Vortex meters, oval gear meters, nutating disc meters, oscillating piston meters, impeller meters, Btu meters, variable area flow meters, differential pressure flow meters.

Model PDLC 400 can calibrate up to four flow meters simultaneously at flow rates of 0,03 to 1515 l/min.
