Hi-Flow Natural Gas Leak Rate Measurement
The Hi Flow® Sampler is designed to measure the rate of gas leakage around various pipe fittings, valve packings, and compressor seals found in natural gas transmission, storage, and compressor facilities. This is accomplished by sampling at a very large flow rate (8 to 10 SCFM) to completely capture any gas leaking from the component. Then by accurately measuring the flow rate of the sampling stream and the natural gas concentration, it is possible to calculate the rate of the gas leak.
We at Bacharach are very excited about our partnership with the Gas Technology Institute in the commercialization of their patented Hi Flow Sampler. Many changes and enhancements have been made from the original instrument including: intrinsic safety; data logging, and instantaneous leak-rate display just to name a few.
Why Use the Hi Flow Sampler?
- Allows ranking of gas leaks in leak-rate order
- Allows users to determine if the potential savings in lost gas by repairing a leak
- Allows users to determine payback periods for particularly expensive repairs
- Allows more cost-effective use of your maintenance budget
- Identifies problem areas
- Determines baseline leakage conditions
- Provides permanent record of leakage and repair
- Greenhouse gas credits
- Pays for itself in recovered gas
