Intelligent integrated vortex flowmeter is based on Carmen (Karman) vortex principle to measure the volume flow of gas, steam or liquid, the volume flow rate or mass flow meter. It can be used as the flow transmitter in the automatic control system.
The instrument adopts differential advanced technology, with isolation, shielding, filtering and other measures to overcome the similar products of poor shock resistance and small signal disturbance data, and uses a unique sensor package technology and protective measures, to ensure the reliability of the product. There are two basic types of products: the basic type and the compound type, and the basic model can be used to measure the single flow signal. Each type has a whole, split structure to adapt to different installation environment.
Features
No moving parts, long term stability, simple structure, easy installation and maintenance
The utility model is characterized in that the utility model is provided with an anti disturbance circuit and an anti vibration sensing head
Ultra low power single chip microcomputer technology, 1 3.2V10AH lithium battery can be used for more than 5 years
The nonlinearity of the instrument coefficient is corrected by software to improve the measurement accuracy
Small pressure loss, wide range of measurement
Using EEPROM to power down the cumulative flow protection, protection time is greater than 10 years
Application scope
The instrument can be widely used in large, medium and small variety of pipeline water supply and drainage, industrial recycling, sewage treatment, oil and chemical reagents and compressed air, saturated and superheated steam, natural gas and various media flow measurement.
