EX800 Series Insertion Electromagnetic Flow Sensor by Seametrics

EX800 Electromagnetic Flow Sensor by SeametricsEX800 Electromagnetic Flow Sensor for conductive liquids.

The Seametrics EX800 series insertion electromagnetic flowmeter has been 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. No moving parts mean 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 the complete mixing of fluids before the meter).

Designed for modularity and versatility, the EX800-Series has a current-sinking pulse output that can be combined with the appropriate transmitter or indicator for the application. For basic rate/total and pulse output, the FT430 is best. For analog output and display of rate and total, the FT440 can be used. Blind analog output is provided by the AO55. The PD10 can be used to divide the pulse for pacing chemical metering pumps. Electronic modules can be wall- or meter-mounted. (Note: PD10 is available only as a wall-mounted unit.) If the EX800 meter is used with a programmable controller, the output signal can be fed direct, with no other conditioning required.

EX800-Series fixed depth insertion meters require special fittings. Factory installation in the fitting ensures correct depth placement in the pipe. The EX800-Series meter can be ordered in a full-power model when a source of electricity is available, or in a low-power model that can run on an external battery with a solar panel. Reverse flow output and impossibility are optional

Features of the Seametrics X800 magmeter

  • Low-flow performance and accuracy superior to any mechanical flow sensor
  • No moving parts to wear out
  • Dedicated fittings for simplicity
  • The retainer clip automatically sets the correct depth
  • The meter extends only about 1/8 of the pipe diameter, minimizing the 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

Suitable applications for the X800 series

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

X800 order combinations

  • Sensor only
  • AO55 mounted on the sensor - blind analog output
  • FT430 mounted on the sensor - basic rate/total and pulse output
  • DL76 mounted on the sensor
  • FT440 mounted on the sensor - analog output and display of rate and total
