Insertion Magnetic Flow Meter

Insertion magnetic flow meter

Insertion Magnetic Flow Meter is the magnetic flow meter that measures the fluid velocity of conductive liquids in applications where hot-tap or insertion installations are preferred. Like, measures the flow velocity of conductive liquids in large diameter pipes.

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.

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 MAG Flow Sensor 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
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.”
