Fully intelligent gas turbine flowmeter with multiple outputs

Project Overview

Ordinary turbine flowmeters only have a 4-20mA current signal in terms of output signal, although this is the standard signal for flowmeters. However, with the development of technology and the update of various systems, there are more requirements for the signals of turbine flow meters, whether they can carry pulse signals, RS485 communication protocol, HART protocol, etc.

The fully intelligent gas turbine flow meter adopts the latest low-power single-chip microcomputer technology and has more choices in terms of output signals, such as output pulse signals, RS485 communication protocol and HART protocol, etc. .

The pulse signal is a common flow meter output signal that calculates the flow rate by measuring the number of pulses of the fluid flowing through the turbine flow meter. This output signal is very practical in some simple applications, such as those that require higher precision flow measurement. RS485 communication protocol is a common serial communication protocol, which can realize serial communication of multiple devices through a pair of twisted pairs. Turbine flow meters using the RS485 communication protocol can communicate with the remote control room to facilitate centralized management and control of multiple flow meters.

HART protocol is a communication protocol for smart devices. It can realize intelligent control of devices through a combination of analog signals and digital signals. Turbine flow meters using the HART protocol can realize intelligent communication with the host computer, and can perform parameter setting, data reading, fault diagnosis and other functions on the flow meter through the host computer.

The above is just a functional iteration of the fully intelligent gas turbine flowmeter in terms of signal output. It also has many other advantages, which we will slowly explore in the future.
