Measurable Media Gas Compressed Air Superheated Steam Saturated Steam Heat Transfer Oil High Temperature Liquids Nitrogen Hydrogen Oxygen Water Applicable Industries Product Description The vortex flowmeter is designed based on the Karman vortex principle, which can measure the flow, temperature, pressure and other parameters of the medium fluid of industrial pipelines according to different types, and has the functions of pulse frequency output, 4-20mA analog signal output, RS485 communication, Hart protocol and so on. It is widely used in heating, gas supply, textile, steel, medicine and other industries to measure and control gas, compressed air, steam, nitrogen, heat transfer oil and other media. It is known as Tongjing 15/20/25/32/40/50/65/80 /100/125/150/200/250/300 (300-1000) plug-in Nominal pressure DN15-DN2004.0 (> 4.0), DN250-DN3001.6 (>1.6) Medium temperature °C -40~150,-40~250,-40~350; Accuracy ±1%R,±1.5%R; Plug-in: ± 2.5%R Range 1:6~1:30 Supply voltage Sensor: DC12V, DC24V; Transmitter: DC24V; Battery-powered type: 3.6V battery Output signal Square wave pulse (excluding battery-powered type): high ≥ 5V, low ≤ 1V; Current: 4~20mA Pressure loss coefficient Conform to JB/T9249 standard Cd≤24 Explosion-proof signs Intrinsically safe type: ExdIlia CT2-T5 flameproof type: Ex db IIC T6 Gb Ingress protection Ordinary IP65 type Environmental conditions The temperature is -20°C~55°C, the relative humidity is 5%~90%, and the atmospheric pressure is 86~106kpa Applicable media Gases, liquids, vapors, mixed gases, flammable and explosive gases Transmission distance Three-wire pulse output type: ≤100m, two-wire standard current output type (4~20mA)≤200m: load resistance≤750Ω; RS485/HART≤500m Fully Automatic Inspection And Calibration Equipment In The Factory No Temperature And Pressure Compensation Integrated Temperature And Pressure Compensation Product Upgrades The square fastening screws are reinforced from the normal round to squarefastening columns which can adapt to a higher degree of on-site vibration. Threaded Connection Clamp Flange Connection One-piece Flange Connection Note: Choose Temp And Pressure Compensation For Gas Measurement Gases are highly susceptible to pressure and temperature, which requires accurate measurements, temperature 25ºC and standard atmospheric pressure. However, field conditions often can not be satisfied, therefore, it is necessary to involve temperature and pressure compensation.
