  • Instruction Manual H GS – NH3 Leakage Sensor

    HBGS fulfils the requirements for gas leakage measurement in accordance with F-GAS regulation EU/517/2014. HBGS detects NH3 (R717) in a range of 0… 500 ppm. It is an independent unit that must be supplied with 24 V DC. It has 3 built-in digital alarm outputs and 1 analogue 4… 20 mA output. The sensor can be set up using a PC with the HB Configuration Tool – Requires HBGS-NH3-ServiceKit. Note:

  • Measurement of NH3 Concentrations in Stack Flue Gas Using

    Introduction. The ammonia (NH 3) gas is injected to remove the NOx and thus reduce the NOx concentration in the stack flue gas.. With conventional NH 3 analyzers that perform measurements indirectly, NH 3 concentrations are obtained through a sampling system.

  • Measurement of NH3 Concentrations in Stack Flue Gas Using

    The ammonia (NH3) gas is injected to remove the NOx and thus reduce the NOx concentration in the stack flue gas. With conventional NH3 analyzers that perform measurements indirectly, NH3 concentrations are obtained through a sampling system. Therefore, there are problems with the maintenance and running costs of the sampling system, and time delays in measurement. The TDLS8000 Laser Analyzer is the solution to all these problems. | Yokogawa Electric Corporation

  • NH3 Precision Anhydrous Ammonia Application for Systems

    Jan 27, 2015 · Things to Know About Anhydrous Ammonia (NH3) Anhydrous ammonia is a colorless non-flammable liquefied gas. Its vapor is lighter than air and has the same pungent odor as household ammonia. Although ammonia vapor is lighter than air, the vapors from a leak may hug the ground appearing as a white cloud.

  • How to Establish an Acceptable Leak Rate - Leak Testing

    • The characteristics of the hole (or leak) that determine whether it will leak are the smallest diameter in the hole path, the path length of the hole through the part material, surface tension, and the surface finish of hole (leak). Hole Size - The smallest opening in the flow (leak) path controls the rate of flow through the path.

    Note this is a pinhole leak not a pinhead leak which would be about twice the diameter. Using dcastoexcellent formula and noting that the diameter of the pipeline and the rate through the pipeline have nothing to do with the question, unless the pipeline diameter is approaching that of a pin, the leak rate through the pinhole is about 120 SCFH.
