8. it or below it This condition happens in a straight long tube when the velocity of the fluid is not high A gas leaking out of a straight and long tube will not generate as much sound as if it were leaking out of a small crack because the flow is not turbulent The intensity of sound generated at a leak is a very complex function of the viscosity the tem perature the speed the fluid is moving the Reynolds number the pressure differential across the leak and the physical dimensions and characteristics of the orifice This is why it is impossible to quantify the size of a leak with ultrasonic technology A smaller leak may generate more sound than a larger one The Tru Pointe 2100 detects ultrasound NOT the presence of a specific gas It is NOT a gas Sniffer Because of this fact the Tru Pointe 2100 can function in areas where heavy wind or a concentration of fumes renders other detectors useless WARNING Ultrasonic detectors will not indicate a leak if there is no turbulent flow producing sound when checked If you suspect a toxic gas natural gas or other combustible gas leak and it is not detected by the Tru Pointe 2100 do not assume it doesn t exist and use another method as verification there is no gas leak present 15 Tru Pointe 2100 Instruction 0028 9003 5 Care and Service The Tru Pointe 2100 is constructed of durable impact resistant ABS however it is also a precision electronic test instrument which shoul
