Intelligent integrated display vortex flowmeter is a new intelligent instrument with multi-function and integration, which is developed with advanced low-power MSP430 chip as the core. The converter has multi-point coefficient correction function. This series of products adopt segment code LCD display with high contrast and low power. Two display units are optional. A variety of electrical signal output modes are optional, especially suitable for quantitative control. This series of products can not only display the commonly used volume flow units, but also display the mass flow units by setting the measured medium density. On the basis of the above functions, in order to meet the different needs of users, users can choose the communication function of MODBUS protocol based on RS485 interface.
