Description

CALSENSE FLOW METER FM 1.23B  1 1/4" BRASS TEE  FLOW SENSOR MODEL 250B NEW
The Calsense Flow Meter consists of an impeller and a sensing device, which measures the flow in gallons per minute (GPM). The irrigation controller learns an average GPM value for each station. If a broken head or riser causes the flow to exceed the learned flow rate by a selected percent, the irrigation controller shuts off that station automatically and advances to the next station. When irrigation has finished, the controller marks that one station with a HIGHFLOW alert on the display. During the next irrigation, that station will again come on and a measurement will be taken, if the flow still exceeds the learned average flow for that station, the controller instantly turns it off and again displays a HIGHFLOW alert. Calsense Irrigation Controllers monitor the flow meter continuously and will close a master valve if at any time the flow exceeds the user selected Mainline break number. A Flashing MAINLINE BREAK alert on the irrigation controller will alert the user to the problem. A normally closed or normally open master valve can be used. No irrigation will occur until the MAINLINE BREAK alert is cleared by the user. If a valve does not open, or has a measured flow rate below the flow meter minimum, the irrigation controller will flash a NO FLOW alert on the display. If the backflow preventer or water meter has been turned off, every station on the controller will have a NO FLOW alert. RESTRICTIONS Certain hydraulic restrictions should be considered when designing an irrigation system with the Calsense Flow Meter. Since the irrigation controller independently learns station flow rates, the flow meter must be installed in a pipe through which only the water regulated by the irrigation controller flows. Therefore there must be isolated supply lines for each controller. If a loop system exists or if several irrigation controllers are fed off of one main line, the –FL option should be recommended.
