In recent years Seametrics flow measurement has become a leading manufacturer of electromagnetic meters (mag meters) in a variety of designs suitable to a wide range of applications.  These include insertion, spool, and low-flow chemical-resistant mag meters.

Magmeters are designed to measure the flow of fluids with conductivity greater than 20 micro Siemens.  For best accuracy, the conductivity of the fluid as it passes through the meter must remain uniform. Wide variations in conductivity result in “noise” or jumpy readings, resulting in inaccurate flow rates and totals.

In control applications such as PLCs, motor drives, some injection pumps, 4-20 mA converters and other devices, a frequency proportional to flow rate (rather than a pulse output which relates to volume) is usually required. For compatibility with these devices, a High Frequency output (0-150 Hz at full flow) is available. 


You can instal  a Seametrics EX215 stainless hot-tap insertion magmeter with bidirectional sensor in a 42” pipe supplying water to the hydrogenerator.  The meter is housed in an underground vault, and the sensor measures forward flow to the generator and reverse flow when, with changing system demands, booster pumps send water out to other distribution zones. This meter replaced a competitor’s aging full bore magmeter.


Why must chose the Seametrics Insertion Magmeter ??
  • “No moving parts” It means it is suitable for water that much dirt
  • Insertion Seametric Flow Meter is  very simple and Cost down Installation
  • Low cost maintenance can less down time equipment
  • More cheap dipenad on Full bore size magmeter
  • The hot-tap installation saves significant excavation and downtime costs.
  • Can be installed in a large pipe up to 48 "
Kind Of Insertion Magmeter :

EX 80 Insertion


EX800-Series insertion electromagnetic flowmeters are designed for use with conductive liquids in 1 to 12” pipe. A choice of materials (stainless steel, brass, and PVC) allows the meter to adapt to a range of temperature, pressure, and corrosive environments. 

The EX800 is highly suitable for difficult applications with changing viscosities and pulsating flows, such as air-driven diaphragm pumps. With no moving parts, these meters can be used in “dirty” applications where debris would foul a mechanical meter. Like all magmeters, when used in chemical injection applications, these meters should be installed upstream of the chemical line (or far enough downstream to allow complete mixing of fluids before the meter).


Down Load


EX110/EX210


The complete lack of moving parts of the EX100/200-Series insertion flow sensor is the source of its reliability. Brass and stainless steel models withstand a variety of temperature, pressure, and chemical conditions. 

The EX-Series has no rotor to stop turning in dirty water and there are no bearings to wear out. A rapidly reversing magnetic field is produced in the lower housing. As the fluid moves through this field, a voltage is generated that is measured and translated into a frequency signal proportional to flow rate. This square wave signal can be sent directly to a PLC or other control or can be converted using any of the Seametrics family of indicators and converters

EX150/EX250


The complete lack of moving parts of the EX100/200-Series insertion flow sensor is the source of its reliability. Brass and stainless steel models withstand a variety of temperature, pressure, and chemical conditions.

A modular system of electronics can be attached directly to the flow sensor or remotely mounted. The Seametrics FT420 provides full indication of rate and total, plus 4-20 mA output. The AO55 provides blind 4-20 mA output, and the DL76 is a battery-powered data logger.
