1. Product
LUGB vortex flow meter is a kind of velocity flow meter, which is designed based on Karman vortex principle. It is mainly used for flow measurement of gas and fluid in industrial pipelines, such as flow control and measurement of gas, steam or liquid and other media.
LUGB vortex street flow meter can achieve the following functions according to the selection: measuring the temperature, pressure, instantaneous flow and cumulative flow of medium fluid in industrial pipelines, and has pulse output, 4-20ma analog signal output, RS485 communication (Modbus RTU protocol), Hart protocol, GPRS of Internet of things and other functions.
Vortex flowmeter is widely used in heat supply, gas supply, chemical industry, environmental protection, metallurgy, textile, steel, pharmaceutical, paper making, drainage and other corporations to superheated steam and saturated steam, compressed air and gas (oxygen, nitrogen, hydrogen, natural gas, coal gas, etc.), water and liquid (such as: water, gasoline, alcohol, stupid class, etc.) of the measurement and control.
2. Features
Ø The main body of the product has no moving parts, high reliability, long-term stability, simple structure and easy maintenance.
Ø The output of the sensor is pulse frequency, which is linear with the actual flow rate of the measured body, zero point no drift, and the performance is very stable.
Ø The structure forms are various, including pipe type, plug type flow sensor and so on.
Ø The measurement accuracy of conventional liquid is ±1.0%.The accuracy of the gas measurement was ±1.5%；
Ø The pressure loss is small (about 1/4 to 1/2 of orifice flowmeter), which belongs to energy-saving flow meter
Ø Flexible installation mode, can be horizontal, vertical or inclined to different angles according to different process pipeline；
Ø Circuit adopts a variety of protection mode, anti-surge, strong adaptability；
Ø High precision probe, piezocrystalline vortex sensor, stable signal. The 316L stainless steel sensor shell has strong corrosion resistance and good intercrystalline corrosion resistance. It also has good corrosion resistance to alkali solutions and most organic and inorganic acids；
Ø Long life lithium battery: equipped with 3.6v high poly lithium battery, with high storage energy density, the service life of more than 1 year；
Ø Products high and low temperature adaptability, environmental protection and other advantages；
Ø Wide measuring range, measuring range ratio up to 1：45；
Ø Within a certain Reynolds number range, the output signal frequency is not affected by the physical properties and component changes of the fluid, and the instrument coefficient is only related to the shape and size of the vortex generator，There is no need to compensate when measuring the volume flow rate of the fluid condition.
