Test Rigs with Critical Nozzles for Gas Meter¹

Product Description Product Description The device uses a sonic nozzle as a standard for accurate, automatic and efficient verification of speed flowmeters, volumetric flowmeters, mass flowmeters, and ultrasonic flowmeters. It is suitable for use in units such as measurement and testing institutions, gas companies and gas flowmeter manufacturers.The device consists of a sonic nozzle, a stagnation container, a back pressure container, a buffer container, a flow meter quick switching mechanism, and a bus measurement and control system. Our Advantages 1. Sonic nozzle multi-filter, clean without clogging.2. The sonic nozzle accurately locates and measures leakage.3. Temperature and pressure measurement accuracy is high, the bus real-time high-speed transmission of measured values.4. The small-caliber flowmeter rotates and switches clamping rapidly, no need to replace the measuring section, saving space.5. Pneumatic clamping table, easy and efficient.6. The computer intelligent control selects the best nozzle combination to verify the different flow points.7. Intelligent automatic verification. Product Parameters ItemParametersItemParametersUncertainty≤0.5%,≤0.3%Nozzle Discharge Coefficient≤0.2%Flow Range(0.06~7000)m3/hFlow Stability<0.1%Flowmeter SpecificationDN15 ~ DN300 (Customizable)Pressure Transmitter(-100~100)kPaTemperature Test(0~50)oCEnvironment Temperature(20±2)oCHumidity Test45%~70% Power Supply380V±38V AC 50Hz Detailed PhotosCasesPackaging & ShippingCompany ProfileEstablished in early 1990, YiBin Mechatronics Research Institute is a national high-tech enterprise that is concerned with the design and development of opto mechatronics products and intelligent instruments and meters.
