BetaGauge330

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.

The new ranges offer the same ±0.025% of full scale accuracy (6 month specification) as the previously offered gauge ranges (30, 150 & 300 PSI).

Some of the other useful features of the 330 are

• built-in loop calibrator (input and output
• large multi-variable display
• 24 VDC instrument power supply
• automatic pressure switch test
• available gas custody meter calibration kit
• 17 engineering unit displays
• external pressure module compatible

For a surprisingly low cost in a surprisingly small and lightweight package, the BetaGauge 330 has a lot to offer.

Did you know that the accuracy and validity of natural gas custody transfer metering is covered under the US Sarbanes Oxley law?

I didn’t either until I read this informative post by Jim Cahill over at the Emerson Process Experts blog.

Here’s my short take on what’s required to do a professional job at custody transfer metering for many industries.

• Proper design and installation of metering equipment, which includes selecting the right equipment in the first place. This is a very competitive market and there’s plenty of great hardware available. So, this really boils down to quality installation design and implementation.
• Routine and regular verification of the performance of the system. This is where Martel comes in the a range of useful calibration products such as the BetaGauge 321A. Our calibrators have the performance, reliability and features needed to do a great job of calibrating gas custody transfer systems.
• Technicians who are professionally trained professionals. This may be the hardest piece of the puzzle to fit in. Finding, keeping and motivating quality personnel is a major challenge for corporations world-wide.

It’s ironic that one of the events that instigated the Sarbanes Oxley Act was the implosion of Enron Corporation, a company that started out in the natural gas energy business.

BetaGauge 321 Dual Range Pressure Calibrator

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.
