Insertion magnetic flow meter Features


For applications where the Insertion magnetic flow meter will be installed in pressurized pipes, use the optional Hot Tap Installation Hardware Kit.
It includes a branch outlet, close nipple and 1-1/4″ full port ball valve.


The Insertion Magmeter installs in the pipe through a full port ball valve so the sensor can be easily retracted without having to shut down flow or drain the system. The insertion depth is adjustable according to the pipe diameter. An insertion depth gage is supplied with each flowmeter.


The sensor structure of the electromagnetic flowmeter is relatively simple, and it is one of the flowmeters with the lowest energy consumption in the flowmeters. There are no moving parts in the measuring tube and no throttling part that blocks the flow of fluid and does not cause any additional pressure loss when the fluid passes through the flow meter.

Insertion magnetic flow meter Applications

Raw Water

A Municipal Power Plant was required to monitor its usage of raw water from the Intercoastal Waterway. Lines varied in size from 36 inches to 64 inches and were approximately 10 feet underground.

Install Insertion magnetic flow meter​ via a “Wet Tap” procedure to measure the intake and return of the raw water lines. The meters were required to operate underwater (IP 68) due to flooding conditions. The electronics converter was installed in a control room 300 feet away from the sensors.

Food Industry

The sensor of the electromagnetic flowmeter is easily disassembled, which is convenient for cleaning and is convenient for steam sterilization on a regular basis. Therefore, in the health industry, electromagnetic flowmeters must comply with hygienic specifications.

Our product is widely used in these industries:

  • Potable Water
  • Water Distribution
  • Pumping Stations
  • Filter Balancing and Backwash
  • Reclaimed Water
  • Treated Water
  • Irrigation Water
  • Cooling Water
  • Raw Water

Insertion Magnetic Flow Meter Working Principle

How does a magnetic flow meter work

Faraday’s Formula
E is proportional to V x B x D where:

E = The voltage generated in a conductor
V = The velocity of the conductor
B = The magnetic field strength
D = The length of the conductor

The insertion magnetic flowmeter is based on Faraday’s law.When measuring flow, a liquid flows through a magnetic field perpendicular to the direction of flow and induces a voltage proportional to the average flow rate (volume flow). Its induced voltage signal is detected through two electrodes that are in direct contact with the liquid. Voltage signal will be transmitted to the smart transmitter through a dedicated cable. The smart transmitter performs calculations based on the magnitude of the electric potential and the mathematical model of the electromagnetic flow. And converts it into a flow signal for on-site display. Including instantaneous and cumulative quantities can be display. Then output the standard 4 ~ 20MA and 1 ~ 5VDC signals to the flow secondary meter or DCS.

Water Flow Meter Types

Water Flow Meter Types

Water flow meter types are: Electromagnetic (magnetic), Turbine, Ultrasonic, and DP. Coriolis and Oval Gear flow meters can also work for water flow measurement.

Flow Meters for Domestic Water-Potable Water-Drinking Water

Flow Meters for Domestic Water

Potable water flow meter also called Drinking water. Potable water flow meters are important for Domestic industries. Accurate flow measurement is essential to cost-conscious drinking water and potable water system. From water storage, transmission lines to raw water, water treatment and more. Reducing costs and improving flow control is on everyone's mind. Depending on the requirements of your domestic water applicaiton, there are lots of options. Including: Insertion and inline electromagnetic flowmeters.

Wastewater flow meter

Wastewater flow meter

Wastewater Flow meters are flowmeters for water and wastewater treatment. Electromagnetic flow meters are suitable for open channel and underground industrial water pipes. Magnetic flow meters can be Remote type, compact type, insertion type. And ultrasonic flow meters are another choice, if you can not change your pipes. Both ultrasonic flow meters and magmeters are inline flow meters.

digital water flow meter

Digital Water Flow Meter

Digital water flow meter, is the electronic flow meter, which display the flow rate of water. Different Industrial liquid, different pipe for 1 inch, 2 inch, use different flow meters. The different sensors include turbine, ultrasonic, orifice plate, venturi, or with shut off switch. All these flow meters, with LCD display, 4-20mA output, or other outputs. The different designs of the flowmeters have a variety of applications.


What is the insertion type electromagnetic flow meter?

The insertion electromagnetic flowmeter is composed of insertion electromagnetic sensor and electromagnetic flow converter used to measure the conductive liquid that electrical conductivity is greater than 5 us/cm.
Insertion Type Electromagnetic Flow Meter is an ideal solution for water flow measurements in large diameter pipes. Most economical as compared to its counterpart in full bore measurement or ultrasonic measurement. Insertion Type Electromagnetic Flow Meter is an ideal solution for water flow measurements in large diameter pipes.

What is the insertion magnetic flow meter principle?

The Insertion Magmeter operates based on Faraday’s Law of electromagnetic induction: as flow velocity of liquid increases through the magnetic field generated by the sensor head of the flow meter, electrodes measure the voltage increase to calculate flow. Accurately Four electrodes measure the induced voltage on opposite sides of the sensor. The voltage readings are sampled and averaged.

How to determine the available straight pipe diameters?

For each application, locate the longest straight, unobstructed section of pipe (no bends, tees, valves, other insertion probes, size transitions). The longest straight pipe run in inches divided by nominal pipe size in inches equals “diameters of straight pipe.”
