Card mounted pulse output vortex flowmeter
1、 Overview of Vortex Flow Meter:
BY-LUGB typeVortex FlowmeterIt is a volumetric flowmeter that measures the volumetric flow rate, standard condition volumetric flow rate, or mass flow rate of gases, vapors, or liquids based on the Karman vortex street principle. And it can be used as a flow transmitter in automation control systems.
The differential technology used in this instrument, combined with isolation, shielding, filtering and other measures, overcomes the problems of poor seismic resistance and small signal data disorder of similar products. It also adopts unique sensor packaging technology and protective measures to ensure the reliability of the product. There are two types of products: basic type and composite type. The basic type measures a single flow signal; The composite type can simultaneously measure temperature, pressure, and flow rate. Each type has a whole or split structure to adapt to different installation environments.
2、 Characteristics and Applications of Vortex Flow Meter:
characteristic:
No movable parts, long-term stability, simple structure for easy installation and maintenance
Adopting anti-interference circuit and anti vibration sensing head, it has certain anti environmental vibration performance
Using ultra-low power single-chip microcomputer technology, one 3.2V10AH lithium battery can be used for more than 5 years
Correction of instrument coefficient nonlinearity by software to improve measurement accuracy
Low pressure loss and wide range of measurement
Using EEPROM for power down protection of accumulated traffic, with a protection time greater than 10 years
Purpose:
This instrument can be widely used for measuring the flow of water supply and drainage, industrial circulation, sewage treatment, oil and chemical reagents, compressed air, saturated and superheated steam, natural gas, and various liquid gas media in large, medium, and small pipelines.
