HQ 993/994 серии V-Cone счетчик

1.summary Our V-cone is concerned by more and more customers as the new product of differential pressure flowmeters. The throttle devices is unique V-shaped cone, to compare with other differential pressure flowmeters, it can overcome the shortcomings of other throttle devices, is a breakthrough innovation. To compare with traditional throttle devices, geometric form of cone has many advantages, such as: high accuracy, wide range ability, small pressure loss, not afraid of plugging, no straight pipe of request, etc. It can achieve temperature and pressure compensation, and compose mass flow measurement system. It used under different working environment, especially to measure more flux, low pressure, high wet gas and coke oven gas, natural gas and other dirty liquids in industry. 2.principle The principle of V-cone flowmeter is the same as that of a common differential pressure type flowmeter, and it is based on the Bernoulli’s theorem of the conservation of energy of a fluid. Using the continuity formulation and Bernoulli’s theorem of the fluid, you can carry out the mathematics relation of the measuring fluid flux and differential pressure number. The principal theory among these is Bernoulli’s theorem for the conservation of energy in a closed pipe. 3.specifications Type HQ991differentialpressureflowmeter HQ992differentialpressureflowmeter Configuration Medium Gas,liquids,steam Accuracy ±1%(±0.5%) DNrange 50mm—Φ3000mm Mediumtemperature -100°C 300°C -100°C 500°C Ambienttemperature Temperature:-40°C 55°C,humidity:5% 90%,atmosphericpressure:86 106Kpa Ex-proof Exd IIBT2 T5 Protectclass IP65 Output 4-20mA,RS485withHQ915flowratecalculation Material Stainlesssteel(1Cr18Ni9Ti),316L Nominalpressure <2.5Mpa <20Mpa Feature uTomeasuregas,liquid,steamandvariousmedium uInsertiontypecaninstallanddismantlewithoutstoppingflow uLowenergyconsumption uNomaintenance uInnovativedesignofsensor,uniquestructure,integrateddesign,highintension,forhightemperatureandhighpressure uUseforindustrialgasandotherdirtymedia uAdapttovarioussizesofcircularorquadratepipes uOpeningsmallhole,lowstraightpipeofrequest
