Flow Dynamics - Model PDLC 400 -Positive Displacement Liquid Calibrator
The Positive Displacement Liquid Calibrator (PDLC 400) provides calibration for multiple meters 2-1/2` 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.

- The precision cylinder on the PDLC 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
- 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
