What is a digital water flow meter?

A Digital Water flow meter is a flow meter that can display the water flow rate, and have the output for the flow rate. Like 4-20mA output, HART, RS 485, and so on. Digital Water Flow Meter is also called Electronic Water Flow Meter. Digital Water Flow Meter is widely used in industrial water and household water measurement. Most of the Sino-Inst flow meters are digital water flow meters. Like the electromagnetic flowmeter, Portable ultrasonic flow meter, Turbine flow meter…..

The water flow meter is an instrument specially used to measure the flow of water in pipes. You can get many different types of water flow meters from your facility.

When used in certain applications, each flow meter has its own advantages. For many pipelines and similar systems, the water must be maintained at a specified flow rate to ensure the effective operation of the system.

What is a water flow meter?

At low flow rates, the speed of the water may be so low that suspended solids settle to the bottom of the pipe, which will deteriorate the efficiency of the pipe and eventually lead to the accumulation of contaminants, which can cause damage.

Since water flow meters can be used in a wide range of applications, there are many reasons to need these flow meters.

On the one hand, knowing that the fluid is in the right place at the right time is very beneficial to ensure that operating costs and efficiency are maintained.

These meters can also be used to ensure that fluids are kept in motion or to determine if the tank is properly balanced.

Any drop in the flow rate may indicate that the water quality is deteriorating and requires treatment.

In some applications, accurate flow measurement is critical to product quality and the health and safety of the final product. These meters are relatively easy to install in the pipeline, depending on the type of meter you choose.

Water flow meter types

Water flow meters are flow meters that can diaplay the flow rate of industrial water pipe.

A water flow meter measures the amount of water flowing through a pipe. We have several kinds to choose from, depending on the application, maintenance needs, and budget.

There are four common water flow meter types:

Turbine (also called mechanical), Vortex, Ultrasonic, and Magnetic. We will tell you everything you need to know about them and help you choose one for your application.

First, you should know the flow meter working principles.

Flow Metering Principalples

  • Differential Pressure Flowmeters
  • Velocity Flowmeters
  • Positive Displacement Flowmeters
  • Mass Flowmeters
  • For Open Channel Flowmeters – weirs, flumes, submerged orifices, current meters, acoustic flow meters, and more

Types of water flow meters

Turbine/mechanical flow meter to measure water flow

Turbine flow meters easily become the most common flow meters around, mainly because these flow meters are more affordable than other types.

The mechanical flow meter measures the water flow through the rotation of the turbine, which uses a basic propeller, blade or split flow design. The flow rate of water is equal to the speed of the blades.

If mechanical flow meters are to be used, they may become clogged if the water is dirty or more contaminated than expected.

Therefore, you probably should not use this kind of flowmeter to measure the flow of slurry. Since these flow meters can become clogged, they are more frequently maintained than other flow meters.

Vortex flowmeter measures water flow

The vortex flowmeter is a unique flowmeter that measures the flow of water by using vortex flow.

When the fluid pushes over the obstacle, it will produce a vortex and form a vortex. The flowmeter is equipped with a sensor tab. As long as the vortex flows through the sensor tab, the tab will bend, which will produce a frequency output indicating the flow rate of the water.

If you decide to choose a multivariable vortex flowmeter, it can measure up to five different variables that are useful for your specific application.

These variables include mass flow, temperature, density, flow rate and pressure. These meters are especially suitable for large pipelines.

Ultrasonic flow meter to measure water flow

Ultrasonic flow meters are designed to use ultrasonic technology to measure the speed of water as it passes through the pipeline.

You should understand two basic types of ultrasonic flow meters, including runtime flow meters and clamp-on ultrasonic flow meters.

If you choose a run-time flow meter, send a standard ultrasonic signal downstream before sending another signal upstream. These two signals are then compared to determine the water flow rate. This is mostly a pipeline water flow meter. It is often used for household water.

For clamp-on ultrasonic flowmeters, can be placed outside the pipe and are designed to emit acoustic pulses through the pipe wall in order to receive the measured value. Since they can be installed outside the pipeline, they can be used for almost any application and can be used with larger pipelines.

Electromagnetic flowmeter measures water flow

The electromagnetic flowmeter can measure the speed of water by using a simple magnetic field.

When water passes through a magnetic field, a voltage is generated. In this way, higher flow rates always generate more voltage when sent through the electromagnetic flowmeter. The electronic system connected to this meter will receive the voltage signal and convert it into volume flow.

Remember that the water needs ions to generate voltage, which means that the electromagnetic flowmeter cannot be used with pure water without pollutants.

What is the difference between a flow meter and a water meter?

Flow meter usually refers to industrial flow meters. Water meter usually refers to residential water meter.

Industrial VS residential digital water flow meter

1. From a functional point of view. Industrial digital water flow meter mainly measures instantaneous flow. It is a real-time state. It can understand the usage of each site. And can output pulses, 4~20mA, etc. Residential digital water flow meter is mainly a cumulative function, generally cannot see instantaneous flow .

2. From the cost point of view. The manufacturing cost of the Residential Digital Water Flow Meter is relatively low. The cost of an Industrial Digital Water Flow Meter is generally relatively high.

3. In terms of quality. Relatively speaking, the Residential digital water flow meter has poor accuracy. It cannot withstand high pressure and high temperature, and cannot output linear signals. It cannot participate in the automation control of modern industry. The industrial digital water flow meter can do the above.

4. From the point of view of usage. Residential digital water flow meter only measures water and is not used to measure gas. And some liquid media water meters cannot be used. Industrial digital water flow meter liquids (water, oil, turbid liquids, etc.) can be measured.

Of course, Residential digital water flow meters can realize various functions such as prepayment. Remote data transmission. Remote valve control. Step water pricing, etc. It is a must-use metering product for residential homes.

How do you measure the speed of the water?

Normally, like the Domestic water, industrial water, raw water, ground water, urban sewage, industrial wastewater, the processed neutral pulp, pulp slurry, etc.

We need to know the flow rate. We know the flow, we can analyze the water flow, control the flow, and so on.

For industrial water, most time is in the pipeline. Sometimes in the open channel.

  • For pipe flow measurement, we can install a flow meter on the pipe.
  • If the pipe can be changed, we can install a pipe flow meter or a flange to mount.
    • Electromagnetic flowmeters, turbine flowmeters, are all installed in this way.
  • If the pipe diameter is large, we can choose to install a plug-in electromagnetic flowmeter at a lower cost.
  • If the pipe cannot be changed, we can install the ultrasonic flowmeter, which is convenient and quick.
  • For open channel flow measurement, we can specialize open channel flowmeters. If you need to purchase an open channel flowmeter, you can contact us to customize it according to your requirements.
