Seametrics EX90 Insertion Electromagnetic Flow Meter

Description

The EX90-series battery powered, insertion electromagnetic flow meter is designed for use with conductive fluids in 4”–12” pipe. The EX90’s stainless steel body allows the meter to operate in a wide range of temperatures, pressure, and corrosive or dirty environments. The EX90 is highly suitable for difficult applications. With no moving parts, these meters can be used in “dirty water” applications where debris would foul a mechanical meter. If the EX90 meter is used with a programmable controller, the output signal can be fed direct, with no other conditioning required. Rate and total units can be set via the front panel touch key pad by the user. Bidirectional flow is standard with totals available in forward, reverse, net, batch forward and batch reverse.

The EX90 is battery powered with an output cable available for transmitting the pulse signal to remote devices. The EX90 can be ordered with a saddle or weld fitting designed to accommodate a wide range of pipe sizes and types while ensuring correct placement in the pipe. In addition, an optional internal data logger allows local storage of flow history. The EX90 is also ideal for replacement of mechanical style propeller meters.
