Recalibration, regular inspection and maintenance are important requirements for a safe and reliable operation of flow measuring instruments. TrigasDM supplies tailor-made solutions according to different functional principles for your application. Since such calibrators are mostly customized, we are happy to talk to you about your special application.

We offer Bell Provers, Sonic Nozzles and LFE - Laminar Flow Elements but we not only offers standard calibrators for testing flowmeters. We always like to talk to our customers about special applications and thereby continuously expand our portfolio.

All calibrators have the popular CFlow+ LabVIEW based data acquisition and control software ensures optimal man-machine interface and ease of operation. This PC based, gas calibration system offers truly exceptional accuracy and stability using advanced flow calculation algorithms and compensation techniques.

Bell Prover:

The Bell Prover, a primary standard gas calibration system, is used to accurately measure a displaced volume of any non-hazardous gas at a constant pressure over time so that precise flow rate measurement can be performed.

Specifications:

• Measuring Principle:      Positive Displacement, Primary
• Flow range:        0.5 to 1500 ALPM (0.02 to 55 ACFM)
• Pressure:            up to 5 bar (Unit Under Test)
• Uncertainty:      +0.2% of volumetric flow rate typical
• UUT Inputs:       TTLpulse, magnetic pickoff, RF pickoff, Visual , Analog (0-10v, 4-20mA, etc.)

Sonic Nozzles: 

Sonic Nozzles are internationally recognized as the best Flow Transfer Standard for gas flow measurement and Calibration.

Specifications:

• Measuring Principle:      Sonic Nozzles, Secondary Standard
• Flow range:        10 to 20000 ALPM (0.35 to 715 ACFM)
