Air Leak/Flow Calibrator

       


More features

The Leak/Flow Calibrator allows checking the calibration of both leak and flow instruments.

Portable, compact and easy to use, it is the essential accessory for the verification of the precision and repeatability of all pressure decay leak, mass flow and laminar flow testers.

  
     
 
       Main features
 
   
- Measurement in standard, actual or user defined conditions - Time stamp
- Choice of unit, within the american or international systems - Automatic sleep mode
- Choice of language - Evolutions: Built-in infrared link + a serial link
- Storage of 10 measured values - Accurate needle valve
- Storage of preprogrammed verifications - Portable (battery + charger)
- Easy connection with the test instrument - Strong, waterproof carrying case (in option)
- Alphanumeric display - 1 year warranty

 
   
  Applications
   
- Checking the calibration of all air pressure decay leak, air mass flow or air laminar flow testers
- NIST traceable calibration of all existing leak and flow orifices
- Used during the capability study and regular calibration procedures

 

 

  
Principle of measurement
 
The leak/flow calibrator is a multiple range flow meter, which measures a pressure drop with a differential sensor connected to the terminals of a laminar flow tube. If an air leak flows through the laminar flow tube, a pressure drop occurs whose value is proportional to the flow in a given range set according to your application. The atmospheric pressure is measured, and the measuring element's temperature. All three measurements are computed to give an accurate reading in standard conditions.
