General
The 286-313-500 and 286-313-525 Remote Mount Transmitters allow the transmitter circuitry to be
located separately from the flowmeter and RVDT stator. This may be desirable when a smaller
flowmeter package is required, when the flowmeter is subjected to high ambient temperatures (ie:
environmental chamber), or for any number of other reasons. Both the remote circuit board housing and
the stator housing are fully sealed. The functionality of the remote transmitter is identical to the
standard transmitter. There are some differences in appearance and installation due to the different
housing and extra connections to the remote stator cable: these are addressed in the information below.
Mounting
The cylindrical aluminum stator housing mounts on the flow meter. Care should be taken when
installing and removing the stator housing. The wire of the stator is of fine gauge and can be easily
damaged. Two wrench flats are provided for installing and removing. The stator housing only needs to
be tightened with enough torque to compress the O-ring and prevent unscrewing due to mechanical
vibrations and cable forces. 10-15 ft-lbs. of torque is sufficient. DO NOT OVERTIGHTEN!
The sealed aluminum or polycarbonate NEMA 4 box containing the circuit board has mounting holes in
the four corners that are accessed by removing the cover. The polycarbonate box has 0.175” dia. holes
with space for a 0.265” or smaller head. The aluminum box has 0.185” holes with space for 0.300” or
smaller head. An 8-32 socket head cap screw works well for both.
