Basic Info
Model No.: HLVZ
Product Description
Model NO.: HLVZ Measuring Medium: Gas Accuracy Grade: 1.0G Structure: Integrated Type and Split Type Flowmeter Medium: Liquid, Air, Natural Gas, Steam Sensor: Tube/Flange Measuring Media: Steam Main Application: Water, Wastewater Trademark: U-ideal Origin: Tianjin, China Type: Differential Pressure flow meter Output Signal Type: Digital Type Certification: ISO Installation: Flange Type, Wafer Type, Insertion Type Flow Indicater: Volume Flow and Mass Flow Accuracy: 0.5%, 1% Size: Dn25~Dn3000 Measuring Principle: Mechanics Specification: CE, SGS, ISO HS Code: 90261000 V type flowmeter working principle:
The V-type flowmeters is a differential pressure flowmeters, it get differential pressure to reflect flow rate through throttle. Throttling set is a cone a hanging in the pipeline central. High pressure the static pressure upstream pH (positive pressure) gets from the wall before the cone, low pressure(the pressure downstream) PL (negative pressure) gets from cone central, square root of the differential pressure DP is proportional to the flow.
Main technique parameter of LGVH flow sensor
Accuracy: ± 0.5% (DP transmitter accuracy should be ≥ 0.2)
(β : 0.45 ~ 0.85, when β < 0.55 and range turn down 4: 1, the accuracy is 0.30)
The repetibility: ± 0.1%
Working pressure: 16 MPa, the biggest pressure can up to 42MPa;
Working temperature: -40~700ºC
The environment temperature: -40-65ºC
Straight pipe installation requirements: Upstream 0~3D straight pipe, downstream 0~1D straight pipe.
Wide measure range: 10: 1(standard)
Small pressure loss: The same β Valve, the pressure loss only 1/3~1/5 of orifice plate.
Applicable medium: V cone flow sensor is suitable for almost all the gas and liquid medium.
Successful flow measurement of liquid types:
Gas
Gas: Coke oven gas, blast furnace gas, converter gas, mixed gas, etc;
Natural gas: Including natural gas which moisture content more than 5%;
Various hydrocarbon gas: Alkane and olefin gas, etc;
Various gas manufacturing: Hydrogen, helium, argon, oxygen, nitrogen, etc;
Corrosive gas: Wet chlorine gas, etc;
Air: Including wet and dust air, compressed air etc;
Flue-gas: Flue gas emissions from all kinds of boiler, heating furnace;
Steam: Saturated steam and superheat vapor;
Liquid
Oil: Crude oil, fuel oil, aqueous emulsified oil, diesel oil and so on;
Water: Raw water, drinking water, production water, sewage etc;
Various water solution: Various acid, alkali, salt water solution etc.
Organic chemicals: Methanol, ethylene glycol, and xylene etc.
Special fluid:
Oil + HC gas +sand
Aerated water: H20 + N2 + air; H20 + CO2 etc.
