Steam Mass Flow Meter Overview
The flow totalizer collects, displays, controls, remote transmission, communication, printing, and other processing for various signals such as temperature, pressure, and flow on-site, and constitutes a digital acquisition system and control system. The steam mass flow meter has a liquid crystal and digital display, and various dimensions, suitable for flow integration measurement and control of various liquids, general gases, superheated steam, and saturated steam; quantitative/batch control of media (with start, stop, and zeroing functions), and various flow sensors or transmitters. The steam mass flow meter can be used in conjunction with the controller and can adapt to various measurement and control occasions. The flow totalizer is used in conjunction with various flow sensors or transmitters, temperature sensors or transmitters, and pressure transmitters to measure, display, accumulate, and calculate flow parameters for various liquids, steam, natural gas, and general gases. Alarm control, transmission output, data acquisition, and communication.
The steam mass flow meter is sometimes referred to as a flow meter or flow totalizer. The flow totalizer meter displays the flow rate from either an analog or pulse output flow sensor as well as the accumulated total and grand total volume over time. Flow meters are devices used to measure the flow rate or quantity of a gas or liquid in a pipe. The pulse output dosing flow meter works on the basis of a flow sensor. It shows the data results that people want.
The steam mass flow meter is suitable for measurement, display, control, and metering integration of tap water, oil, liquid, solid fluid, and other industrial process flow parameters that do not need to be compensated. It can receive orifice plate differential pressure input or input signals of various flowmeters such as vortex flowmeters, electromagnetic flowmeters, turbine flowmeters, etc.

Steam Mass Flow Meter Working Principle
The steam mass flow meter is composed of four parts: measurement loop, digital panel meter, regulator, and power supply. The stabilized power supply converts the 220V power supply into a stable DC voltage as the other part of the power supply. The measurement loop processes the signal (voltage, current, etc.) sent by the flow transmitter into a voltage signal. After A/D conversion, the signal is sent to a dedicated central processing unit for processing. Not only to the digital panel meter but also to the regulator. After comparing with the set value, it outputs a control or alarm signal according to the regulation rule.
"Flow totalizer" simple control totalizer has strong anti-interference, intuitive display of LED color interface, can directly receive 4-20mA signal, 0-5V, 0-10V, pulse signal, etc. It has a temperature compensation port and pressure compensation port, can be configured with Modbus-485 communication protocol, and can exchange information with DCS, PLC, and other control terminals, The flow totalizer is a commonly used paperless recorder.
