River Water Flow meter Wmag21 DN 300 is a type of Electromagnetic Flow Meter flow meter, which is one type of flow measurement, the product we will discuss today is the WMAG21 Electromagnetic Water Flow Meter
Definition of Electromagnetic Flow Meter
Electromagnetic flow meter or Magnetic Flow Meter and often called magmeter is a type of flow meter that has no moving parts (moving part). This magnetic flow meter is ideal if used for measuring inhomogeneous fluid flows, dirty liquids, fluids containing mud or for waste fluids or intake water, raw material water, water from reservoirs or rivers that contain a lot of dirt or garbage (plastic, grass or other), so it is quite suitable for use as a waste flow meter.
This magmeter or electromagnetic flow meter can only be used in water applications that have a certain conductivity, in accordance with the rules required by each electromagnetic flowmeter manufacture.
In general, the magnetic flowmeter does not work on hydrocarbon fluids and distilled water (distilled water / demin water). However, it is ideal for measuring the flow of liquids such as slurries and corrosive materials, such as in chemical processes or beverages or thick water liquids such as soy sauce, sauce, syrup and others.
This electromagnetic flowmeter is very suitable for use in flow systems that require very low pressure drops.
The working principle of this type of electromagnetic flow meter is based on the law of electromagnetic induction (Faraday’s Law), namely when an electrically conductive fluid passes through an electromagnetic sensor pipe, the fluid will work as a moving conductor that cuts the magnetic field generated by the magnetic coil of the sensor / transducer, so that an induced voltage is generated.
Introduction
Flowma WMAG21 Electromagnetic series intelligent electromagnetic flowmeter is made according to the law of electromagnetic induction to measure conductivity fluids flowing in pipes such as well water, sea water, wastewater, sludge water, drinking water, acid liquid, food porridge, syrup, sugar water and others.
This liquid is widely used in the food and beverage industry, sewage treatment, river or rainwater drains, water treatment, petrochemicals, power plants, mining, agriculture, automotive industry, cooling systems and other industries.
Flowma wmag21 electromagnetic flow meter has 2 main parts, namely electromagnetic flow sensor and electromagnetic flow transmitter or called Converter. Each part has its own characteristics and functions
Electromagnetic Flow Sensor
The electromagnetic flow sensor has a function to capture the flow that has conductivity by using a pair of electrodes and sends a signal to the converter which will be processed according to Faraday’s law.
Flow Meter Type
Flowma Wmag21 electromagnetic flow sensor has 2 types of installation, namely
Inline Electromagnetic flow sensor
- The installation system is carried out by cutting pipes, while there are several types of connections, namely by flange, thread, wafer and sanitary tri clamp
Insertion Electromagnetic flow sensor
- The installation system is done by perforating the pipe. while the connection is by installing a fitting either with asaddle fitting or welding and the sensor is inserted into the pipe through the fitting. This type of installation is suitable for pipes with large diameters.
There are 2 types of flow converters for electromagnetic water meters, namely the compact or integral type. where the way the converter is integrated with the sensor. For the second type, namely the split or remote type where the installation method is separate from the electromagnetic sensor. To connect the converter with the magnetic sensor, you need a cable whose length is adjusted as needed.
Advantages of Wmag21 River Water Flow meter
Flowma WMAG21 characters
- The measurement of this tool does not depend on pressure, temperature, density, density, type weight, viskcosity
- The flow in the pipe is not disturbed because there are no rotating components in the sensor flow tube.
- Pressure loss can be ignored because there are no components that block the flow of water in the sensor tube so that the presence of solid particles in the liquid does not hinder the flow meter performance.
- It has a standard accuracy of 0.5% and can be better with leprosy orders up to 0.2%.
- Able to fit on a slow flow with avelocity of 0.1 m/s
- The selection of material types for linning and electrode can provide a very wide use of liquid types and is suitable for use for the character of corrosive liquids to abrasiv.
- Can be used for liquids with low temperatures up to 180 degrees Celsius depending on the type and model
- Provides output control in the form of pulse, analog 4-20mA, RS45 to hart communication
