OPTIONS 1S2 AND 2S2: REED SNITCHES. RCM
Flo-Gages can be ordered with either one (Option 1S2) or two
(Option 2S2) reed switches suitable for sensing
the actual flow rate. The switches make or break contacts by
detecting the position of a magnet which is permanently
attached to the pointer mechanism on the flow indicator. This
technique constant correlation
between the flow rate indicator and the flow switch. In addition
it provides extremely reliable flow sensing which is highly immune
to fouling by small particles in the flowing liquid.
Each switch is independently adjustable from 30% to
90% of full scale. Switches are factory set to specified
flow rates (30% to
90% FS if not specified). Switches
are single-pole double-throw for ease in configuring a safety
interlock or control circuit.
Tamper resistant switches are located inside the meter and
accessed by removing the hack cover. Switches are hermetically
sealed in glass and then epoxy potted.
A 1/2" conduit entrance and a built-in terminal strip
are provided for ease of connection.
