PDCL 400 Positive Displacement Calibrator Liquid

Brand: Flow Dynamics

The Positive Displacement Liquid Calibrator (PDLC 400) provides calibration for multiple meters 2-1/2 in. or smaller. Having an integrated Flo-Cal user interface and DAQ system installed on the frame of the calibrator reduces floor space and eliminates the need for a cart. This robust Primary Standard Calibrator incorporates a unique return line cyclone system that filters air entrapment from being re-circulated back into the flow meter under test. All PDLC calibrators have an excellent electronic signal-to-noise ratio providing the highest quality of captured data obtainable. Panel frame coverings are optional along with automatic test section bleed valves.
Features
  • Has separate temperature sensors for the cylinder and test section to correct for changes in volume as recommended by NIST.
  • Have long test sections that can accommodate two turbine flowmeters with flow straighteners in tandem. This is the recommended set-up for a NIST roundrobin calibration check.
  • Comes standard with frequency, voltage and current inputs.
  • Has three rate-control valves for course, medium and fine flow rate control.
  • Provides a filtered pump to return fluid from the test section pan to the reservoir.
  • Provides provides automatic temperature control using a fluid heater plus connections for a chilled water flow loop.
  • The run and return valves are activated automatically by software commands.
