Many people don’t realize that we make a custody transfer flowmeter calibration kit for the BetaGauge 330-30. This adds a high range pressure module and LTP100A RTD probe to the standard calibrator.
The integral pump and internal sensor are used for the differential calibration portion of the flowmeter. A high pressure external sensor is used for the static portion, and, of course, the RTD provides the data for the temperature compensation calibration of the flowmeter.
In addition, it all fits in the normal carrying case for the 330.
