Ultrasonic Flow Meters

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 Meters

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 Meters

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 Meters

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 Meters

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.

Digital flow meter with totalizer

The flow totalizer mainly refers to a display and control instrument used in conjunction with a flow meter.

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.

What is a Flow Meter and how does it work?

Video source: https://www.youtube.com/embed/_pL7bGEF52s?start=2

A flow meter (or flow sensor) is an instrument used to measure linear, nonlinear,mass or volumetric flow rate of a liquid or a gas.When choosing flow meters,one should consider such intangible factors as familiarity of plant personnel,their experience with calibration and maintenance, spare parts availability,and mean time between failure history, etc., at the particular plant site.

It is also recommended that the cost of the installation be computed,only after taking these stepsThe different sensors include dial, in-line, ultrasonic, orifice plate,totalizing meters, variable area, venturi, or with switch output.The different designs of the flow meters have a variety of applications.

Know More about Flow Measurement

If you need to know the flow rate in you pipe, or river, that when you need a flow meter. So, flow meter is the instrument that can finish the flow measurement.

Flowmeters consist of a primary device, transducer and transmitter.

The transducer senses the fluid that passes through the primary device.

The transmitter produces a usable flow signal from the raw transducer signal.

These components are often combined, so the actual flowmeter may be one or more physical devices.

Different types of flow meters are available for different application,

and depending upon the requirement, a careful selection of flow meter is made.

For e.g., we prefer vortex flow meters flow steam flow measuremnet. And we like the ultrasonic flow meters for non-contact pipe flow measuremnt.

Turbine type flow meter cannot be used for measuring the flow in an unclear liquid

(waste water or corrosive liquids).

Electronic flow meter, are industrial digital flow meters for fluid flow rate measurement. Electronic flow meters types like: MagneticVortex, and Ultrasonic flow meters.

While magnetic, vortex, and ultrasonic–are neither exclusively nor exhaustively electronic in nature. They do represent a logical grouping of flow measurement technologies.

All electronic flow meters have no moving parts, are non-intrusive, and are made by electronics technology.

Magnetic flowmeters, are the most directly electrical in nature, deriving their first principles of operation from Faraday’s law. Vortex meters depend on piezoelectric sensors to detect vortices shed from a stationary shedder bar. And today’s ultrasonic flowmeters owe their successful application to sophisticated digital signal processing.

In line flow meters, also called in-line flow meters (or, flow indicator). In line flow meters are flow meters, which are installed in the flow path of you media pipe, and measure the flow rate.

In-line flow meters coudl be digital and mechanical flow meters. Common in-line flowmeters include turbine flowmeters, electromagnetic flowmeters, and ultrasonic flowmeters. With stainless steel material, analog and 4-20mA output, in-line flow meters can measure and controll inline flow.

Sino’s in-line flow meters are ideal for measurement of gases, fuel, or water based liquids. Applications include: deionized water flow, pickling, compressed gases, harsh environments, coolant lines, residential water and industrial applications.
