Level and Flow Catalog Page17

We highly recommend the following level detectors and flow meters from IMO Industries, Gem Sensors division, for use in both fresh and salt water systems:

Model LS-7, Type VII, PolyPro float switches. Approximately 6” long, 0.5 inches in diameter. The float tip has a travel range of approximately 1 inch. Mounts with 1/2 in. NPT fitting, either through a bulkhead wall plate on in a pcv pipe elbow. These are excellent switches, and easily tolerate high pH salt water environments.

Model RFO2500. Available in either low flow (.1 to 1 gpm), medium or high flow rates, 1/4 or 1/2 inch NPT port sizes. These are excellent, high grade rotating flowmeters, with a see-through port to get a visual confirmation on the impeller performance. Twist lock opening for easy cleaning of rotor. Electrical pulse
output from the flowmeter is directly compatible with our frequency converters. The frequency converter supplies power to the flowmeter, and displays the calibrated flow rate on the built-in LCD readout. The electrical output from the frequency converter is fed to the MCU500 for data logging, monitoring and control of the system.

Lo-Flow Rate Flow Meter (0.5 to 5 GPM), 0.25 NPT

Hi-Flow Rate Flow Meter (4 to 20 GPM), 0.5 NPT

Note: The Lo-flow rate version comes with a restrictor for use with very low flow rates. The restrictor lowers the range by a factor of 5.
