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.
