Digital chemical flow meter

Used for different types of application, a digital chemical flow meter is used to measure the mass or volumetric flowrate of chemicals. The capacity and type of the flow meter is defined by the specific application. They are necessary to monitor liquid flow accurately in water treatment plants, refineries, power generation plants and such others. For repeatable flow measurement there are several different makes and models of digital chemical flow meters, and some of the most popular or commonly used ones have been mentioned next for your better understanding:

Magnetic flow meter to be used as digital chemical flow meter

In this kind of chemical flow meter, firstly a magnetic field be generated and then it will be channeled into the liquid/chemical that goes through its pipe. Here the flow of the conductive liquid by the magnetic field will create a voltage signal which will then be sensed by the electrodes that is situated on the flow tube walls. Electromagnetic flow meters are generally used in water treatment plants and in mining and mineral processing industries. They are also used to measure corrosive and aggressive chemicals like brine, hydrochloric acid, caustic soda, sulphuric acid and more by choosing different liner and electrodes material. Mag meter is a kind of digital chemical flow transmitter, which has digital display, pulse or current output, various communications and protocols, such as HART, PROFIBUDS-DP.,etc.

Digital Turbine flow meter to be used to measure chemical

Turbine flow sensor is a volume sensing device. Thus, it is used for measuring the indirectly and directly passing of different liquids through it. When liquid chemical is passed through the turbine housing, the turbine blades (suspended freely) will rotate providing you with the information you required from it. Turbine flow transmitter is compact in design, can measure high pressure, possesses chemical flow sensors and happens to be reasonably priced. Digital turbine flow meter has great measuring range with high level of accuracy up to 0.5%. Chemical is low in viscosity, clean and low corrosive liquids are measured with its help. So, clean water, diesel, ethanol, different chemical solutions and solvents are measured by this type of chemical flow meter. Digital turbine flow transmitter is powered by 24V DC or battery operated, it has electronic flow indicator to show chemical flow rate and total flow. It also has 4-20mA or pulse output.,etc.

Metal Tube Rotameter with transmitters to measure chemical flow rate

This type of digital chemical flow meter is used for the measurement of flowrate of both gases and liquids. Commonly, it is seen with a float and a tube along with a scale. In this kind of rotameter is tapered, and it is made so in order to provide a variable ring orifice. The rotameter indicator, will show the result which the chemical industries are in need of. It happens to be potable in size and makes related operations quite cost effective. It can measure chemicals like ethylene, sealant, additive, such other chemicals. Rotameter can be equipped with an advance flow transmitter to have digital display also output for process control.

Oval gear flow meter and Coriolis Flow meter to be used as digital chemical flow meter

These two types of chemical flow meter are used to measure high viscous chemical such as molasses, resin, glue, asphalt and such others. They both have huge, jagged flow sensors. With their different outputs and protocols, different processes as seen in chemical plants can be properly controlled. The first kind of flow meter possesses oval gears (usually two) that are used to trap and measure fluids that are highly viscous in nature. Meanwhile, Coriolis flowmeter will have a vibrator and a tube to measure different liquids that has high viscosity.  Both of the two type’s flow meters can be to measure viscous chemical. They both can have digital display and frequency or pulse output.

Besides these, there are many other different kinds of flow meters available. Understanding the purpose and requirement properly will allow you to select the right digital chemical flow meter.
