Gas meter seals - Import export

The installation system consists of high-quality NiroSan® Gas press fittings with yellow moulded sealing rings made of HNBR (hydrogenated nitrile butadiene rubber) and NiroSan® stainless steel system pipes according to EN 10312, DVGW-Arbeitsblatt GW 541 and EN 10312. All NiroSan® Gas press fittings are made of the material 1.4404 / AISI 316L (for moulded fittings) and 1.4408 (for threaded fittings and stainless steel precision castings). The material contains at a minimum of 2.3 % molybdenum and a lower carbon content than the conventional steel quality 316. Thereby these materials are not only of equal value but in addition, material 1.4404 / 316L stands out on account of its considerably higher corrosion resistance. The NiroSan® Gas press system is certified in accordance with and all important European certification bodies.

The test bench is designed for calibration with critically operated nozzles of domestic gas meters or others such as diaphragm gas meters, ultrasonic meters, thermoelectric gas meters. The test bench is specially designed for the calibration of domestic gas meters (bellows gas meters, ultrasonic meters, thermoelectric gas meters). The test bench is modular - 1x6 to 4x6 clamping positions for the gas meters can be combined. Due to the modular design 1 to 12 gas meters can be tested simultaneously. In parallel, up to twelve additional test pieces can be adapted, run in and leak tested. A magazine consisting of three critical nozzles is used as flow transmitter. Optionally, a nozzle drum with nine combinable nozzles can be used. This allows the generation of up to 512 different flow points with highest accuracy.

for small pipe size DN8~DN50 micro mass flow designed to measure the mass and standard flow in small pipe lines in general industry and laboratory

VFM60MV multivariable vortex flowmeters is an integral solution for mass flow /standard flow measurement of steam and gas. Integrated pressure and temperature sensors for density compensation, so it can also measure temperature, pressure, density, mass flow and standard flow. User would only need one flowmeter to measure and read all this parameters, this advantage leads to lower cost and maintaining.

TGF600 Screw-in thermal mass flowmeters for small pipe size gas meausred Inline type can be installed/removed without stopping the line Minimum flow rate down to 0.3m/s, 1:100 super wide turndown ratio No moving part, almost no pressure loss Direct mass flow measurement, do not require temperature or pressure compensation TGF600 Series screw-in inline thermal mass flowmeters measures the gas mass flow base on thermal dispersion theory. It combines COMATE’s advanced technology on transmitter, sensor, filming and calibration, can provide stable and accurate measurement even under harsh industrial applications and require very less maintaining.
