Seametrics EX800 Fixed Depth Insertion Magmeter

 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 water” 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)


  • Low-flow performance and accuracy superior to any mechanical flow sensor
  • No moving parts to wear out
  • Dedicated fittings for simplicity
  • Retainer clip automatically sets correct depth
  • Meter extends only about 1/8 of pipe diameter, minimizing potential for clogging with debris
  • Simple pulse train output can be used with any SeaMetrics signal processing module or sent directly to a PLC
  • Available for pipe sizes 1″ to 12″, in brass, 316 stainless, and PVC


  • Conductive fluids
  • Small pipe applications(1”-12”)
  • Industrial processes
  • Chemical metering pumps
  • Fertigation
