What is a digital flow meter? Digital flow meters are devices used to measure the rate of flow of liquids or gases in pipes or channels. And Digital flow meters support data processing and signal output. Such as temperature and pressure compensation, 4-20mA, RS485, etc. Digital flow meters are more helpful for the monitoring of multi-pipe flow systems.
Different digital flow sensors include turbine, thermal mass, electromagnetic, ultrasonic, orifice plate, venturi. The different designs of the flowmeters have a variety of applications. With 4-20ma, RS485, or others output.
Sino-Inst offers a variety of digital flow meters for flow measurement. If you have any questions, please contact our sales engineers.
If you know enough about the flowmeter. Then you can choose different types of digital flow meters according to your measurement needs.
Choose the Right Digital Flow Meters Types
Magnetic flow meter is also called electromagnetic flow meter, mag flow meter or magmeter. Suitable for the measurement of conductive liquids.
Turbine flow meters are velocity flow meters, also called impeller flow meters. Used to measure the instantaneous flow and cumulative flow of liquids and gases.
Precession vortex flowmeter is a new type of gas flowmeter. It can be used for the measurement of natural gas, propane, air, nitrogen and other gases.
The ultrasonic flow meter measures the liquid flow rate quickly and effectively. There are two types of ultrasonic flowmeter technology: Doppler frequency shift and transit time.
Ultrasonic Gas Flow Meter uses the principle of measuring the transit time of ultrasonic waves in the pipeline. Ultrasonic Gas Flow Meter is an ideal choice for various gas measurements.
Differential Pressure Flow Meter is also called DP flow meter. Differential pressure flow meters use the principle of differential pressure to measure the flow of liquid, gas and steam.
Volumetric Flow Meter, as a mechanical flow meter, is also called Positive displacement flowmeter. It can measure the volume flow of high viscosity and corrosive fluids.
Mass flow meter directly measures the mass flow of the medium passing through the flow meter. It can also measure the density, temperature and viscosity of the medium.
flow meter digital output
Digital flow meters can output flow rate data in different ways, and some of the most common types are:
- Pulse Output: This type of output produces a series of pulses that are proportional to the flow rate. By counting the pulses, you can calculate how much fluid has flowed through the meter.
- 4-20 mA Output: This type of output generates a current signal that represents the flow rate. This signal can be used to monitor the flow rate continuously. Check 4-20mA Flow Meters
- RS-485 or Modbus Output: These are communication protocols that allow the flow meter to send data to a computer or other device.
- Wireless Output: Some flow meters have wireless capabilities that enable them to transmit data over Wi-Fi, Bluetooth, or other wireless protocols.
These different types of outputs allow you to integrate digital flow meters into different systems and applications, making it easier to monitor and manage fluid flow.
Digital flow meter working principle
What is a Flow Meter and how does it work?

A flow meter is an instrument that indicates the flow rate to be measured and/or the total amount of fluid in a selected time interval. Simply put, it is a meter used to measure the flow of fluid in a pipe or open channel.
A flow meter also called a flow sensor, is a device or an instrument used to measure the linear, nonlinear, mass, or volumetric flow rate of a liquid or a gas.
Digital Flow Meter Applications:
Digital liquid flow meter
Digital gas flow meter
Digital flow meter with totalizer
In fact, most Digital Flow Meter’s digital display meters can be regarded as a small totalizer.
The flow totalizer is used in conjunction with various flow sensors or transmitters, temperature sensors or transmitters and pressure transmitters. It can measure, display, accumulate and calculate the flow parameters of various liquids, steam, natural gas, and general gases. Alarm control, transmission output, data acquisition and communication.
It is suitable for measurement, display, control and measurement integration of industrial process flow parameters without compensation, such as tap water, oil, liquid, and solid fluid.
The flow totalizer can receive the orifice differential pressure input or the input signals of various flow meters such as vortex flowmeters, electromagnetic flowmeters, and turbine flowmeters.
