Product Details

Split compensation vortex flowmeter

Measurement medium: liquid, gas or vapor Range: liquid Measurement range: 1.2-2000m ³/h Gas measurement range: 5-11000m ³/h Output signal: pulse signal, 4-20mA signal, RS485 Accuracy level: liquid: ± 1% Gas or vapor: ± 1.5%, ± 1% Medium temperature: -40 ℃~+250 ℃, -40 ℃~+320 ℃ Explosion proof level: ExdIIBT6 or ExiaICT4 Protection level: IP65

Stress type vortex flowmeter is a type of velocity flowmeter widely used in industries such as petroleum, chemical, power, light industry, and power heating. Our company's standard for the production of vortex flow meters is the vortex flow sensor (JB/T9249-2015) and the calibration regulation for vortex flow meters (JJG1029-2016).

Product features

■ No movable parts, long-term stability, simple structure for easy installation and maintenance;

The sensor output is a pulse frequency, which is linear with the actual flow rate of the measured fluid. There is no zero drift, and the performance is very stable. The structural forms are diverse, including pipeline and plug-in flow sensors;

High precision, typically measuring liquids with an accuracy of ± 1.0%; The measurement accuracy of gas is ± 1.5%;

The measurement range is wide, reaching up to 1:20 within the Reynolds number range of 2 × 104 to 7 × 106;

Low pressure loss (about 1/4 to 1/2 of orifice flow meters), belonging to energy-saving flow meters;

The installation method is flexible, and it can be installed horizontally, vertically, and at different angles according to the on-site process pipeline blockage;

Adopting anti-interference circuit and anti vibration sensing head, it has certain anti environmental vibration performance;

Adopting ultra-low power single-chip microcomputer technology, one 3V10AH lithium battery can be used for more than 5 years;

Correction of instrument coefficient nonlinearity by software to improve measurement accuracy;

Using EPROM for power down protection of accumulated traffic, with a protection time greater than 10 years;
