The EX90-series battery powered, insertion electromagnetic ow meter is
designed for use with conductive uids 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 dicult 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 ow is standard with totals available in forward, reverse, net,
batch forward and batch reverse.
The EX90 is battery powered and an output cable is available for transmitting
the pulse signal to remote devices. The EX90 includes a Seametrics saddle
which has been 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 ow history.

Upstream straight pipe is selected during initial setup. Upstream
options are 5X or 10X the diameter and are based on the
amount of straight pipe available in either new or propeller meter
replacement installation. Downstream straight pipe requirement
is 2X the diameter. See programming setup for details.
