Hi Flow Sampler Introduction 1 Introduction 1.1 General Description The Hi Flow Sampler is portable, intrinsically safe, battery-powered instrument designed to determine the rate of gas leakage around various pipefittings, valve packings, and compressor seals found in natural gas transmission, storage, and compressor facilities. A component’s leak rate is measured by sampling at a high flow rate so as to capture all the gas leaking from the component along with a certain amount of surrounding air.
Introduction Hi Flow Sampler the range of 0.05 to 100% gas by volume. A second identical combustibles sensor channel measures the background CH4 level within the vicinity of the leaking component. The final element in the sampling system is a blower that exhausts the gas sample back into the atmosphere away from the sampling area.
Hi Flow Sampler 1.4 Introduction Control Unit Description The control unit consists of an 8 line by 20 character LCD and the four pushbuttons. Figure 1-1. Control Unit 1.

Hi Flow Sampler Operation 3 Operation 3.1 Operating Precautions (Please Read) To ensure that the gas sensors are properly zeroed at startup, the Hi Flow Sampler must be turned ON in clean air (free of combustible gases or vapors). Calibrate the instrument about every 30 days to assure its accuracy. The frequency of calibration, however, may change depending on how often the instrument is used and the amount of gas that was sampled.
Operation 3.3 Hi Flow Sampler Sampling Hose & Attachment Connections Connect the sampling hose to the instrument’s leak-gas inlet by clamping the hose to the inlet as shown in Figure 3-2. Also connect the background gas sampling hose to the unit’s BACKGROUND inlet. Figure 3-2. Hose and Attachment Connections The standard sampling hose is 6 foot long.
Hi Flow Sampler 3.4 Operation Grounding WARNING: To prevent the possibility of a static discharge, the Hi Flow Sampler should be grounded while conducting a leak test. Attach the unit’s grounding clamp to the nearest earth ground. Tip: When not in use, the grounding clamp can be stored by attaching it to one of the shoulder straps. Figure 3-3.
Operation 3.5 Hi Flow Sampler Attachments A variety of attachments are available for the Hi Flow Sampler that simplifies the task of capturing the entire gas leak. Choose the appropriate attachment for the type of component being tested from the ones listed below, and then connect it to the end of the instrument’s main sampling hose. 3.5.
Hi Flow Sampler 3.5.3 Operation Capture Bag This reusable capture bag measures 36" x 36" and can be used to completely surround a component that may have multiple leak sources, or contains a leak source that is difficult to pinpoint or reach. Attach the Hi Flow Sampler’s main sampling hose to the bag by simply pushing the end of the hose into the bag’s hose coupling. A click should be heard when the hose has been successfully connected. Release the hose by pushing in the coupling’s release mechanism.
Operation Hi Flow Sampler This tool is useful in capturing leaks in valve stems and small fittings. 3.5.6 Claw Tool Use this tool when the leak source is spread out over a narrow area, such as a crack in a pipe, square flanges, and cylinder heads. 3.5.7 3-Port Background Gas Sampler Attaches to the end of the background gas sample hose to give better average background gas readings. 3.
