Calibrating gas custody transfer flow computer with the BetaGauge 330 pressure calibrator

Gas custody transfer flow computers that calculate flow by measuring the differential pressure across an office plate require special calibration to perform at optimum accuracy. In custody transfer applications where the buying and selling of commodities like natural gas is involved, calibration checks are performed frequently as a matter of fiduciary responsibility. For the purpose… Read more »

BetaGauge 330 – Rechargeable Battery Pack

Wow! It’s one new thing after another… Most of our calibrators use replaceable and convenient Alkaline batteries either AA or 9V types. They’re readily available in all markets. But, for reasons of economy or ecology, some people prefer rechargeable batteries. We’ve sold these as an option for everything we make. Now, we have a new… Read more »

BetaGauge 330 has absolute pressure ranges

In June, we started shipping the BetaGauge 330 with available absolute pressure internal sensors. The 330 is now available with a 30 PSIA (2 barA) or a 150 PSIA (10 barA) internal sensor. Coupled with the 330’s built-in electric pump, this allows calibration down to about 20% of barometric pressure. If needed an external high… Read more »

BetaGauge 330 for Custody Transfer Calibration

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… Read more »

BetaGauge 330 FAQ – 3

Q. Can the BetaGauge 330 be field recalibrated? A. Yes. The BetaGauge 330 is calibrated through the serial port like many Martel calibrators. Other than a computer with a terminal emulation program (we normally recommend HyperTerminal), a LEM232 serial communications cable is needed along with a URA-1 RTD adapter. Both of these can be purchased… Read more »

BetaGauge 330 FAQ – 2

Q. How often do I need to change the batteries? A. On the BetaGauge 330-150, we have tested the battery life by repeatedly cycling the pump to 150 PSI. Similar to the test for pump life, the cycle went to 150 PSI ten times and then rested for ten minutes.  This is a much higher… Read more »

BetaGauge 330 FAQ – 1

Q. How long does the internal electric pump last? A. Under normal use the BetaGauge 330 internal pump can be expected to last a minimum of 5,000 cycles to full pressure before requiring a rebuild. Since the pump won’t normally always be cycled to full pressure (typically 150 PSI / 10 Bar / 100 kPa),… Read more »

BetaGauge Makes Pressure Switches a Snap

One of the common and more tedious jobs done in the calibration field is pressure switch testing. The new BetaGauge 330 actually makes this job easy and relatively quick. We have put in some special features for this particular task. When the pressure switch function is selected, the calibrator goes into a special high speed… Read more »
