PDCL 60

The Positive Displacement Liquid Calibrator (PDCL 60) provides calibration for multiple meters 1 in. or smaller. The PDCL series calibrators all have automatic temperature control comprising of a fluid heater plus connections for a chilled water flow loop. The primary measuring tube has ample length to facility multiple data points in a single stroke. All PDCL calibrators have a test section pan to trap fluid drainage during meter changes and a pump with filters to return the fluid back to the reservoir. Close coupled valves in the test section reduce the amount of fluid spillage.

Benefits

  • The precision cylinder ensures ample volume to capture stable data at max flow rate
  • Has isolation valves in the test section, which reduce the amount of fluid loss when meters are installed or removed
  • An internal pump is provided to simplify filling and draining the calibrator
  • The system automatically cycles the fluid for mixing of fluids

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 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
