Calsense
Flow Monitoring
Every Calsense CS3000 Irrigation Controller includes the ability to monitor flow real-time, detecting
mainline breaks, broken risers, and closed or stuck valves. This is accomplished through the addition of a
Calsense or third-party flow sensor installed in the mainline after the water meter or backflow
preventer.
Installing a Flow Meter
Note:
The following applies to Calsense FM series Flow Meters. If using a third-party flow sensor, refer
to the manufacturer’s guidelines for proper installation.
When installing a Flow Meter, the mainline pipe is typically sized down to accommodate the fitting of
the sensor. The intended direction of the flow is indicated by an arrow on top of the Flow Meter. There
must be free, unrestricted pipe of the same size as the Flow Meter, with a length of at least 10-times the
meter’s pipe diameter upstream and 5-times downstream of the Flow Meter tee. This applies to
distance from any valve, pipe fitting, water meter, or backflow device. The length of #14-gauge (AWG)
wire connecting the Flow Meter to the CS3000 Irrigation Controller must not exceed 2,000 feet. When
using a 2-Wire POC decoder, the flow maximum length of #14 AWG wire between the Flow Meter and
decoder is 20-feet accessible. Additionally, Calsense recommends housing Flow Meters in a rectangular
valve box marked “FM”.
Flow Meters and Master Valves
The Flow Meters and Master Valves feature establishes the points of connection typically consisting of a
master valve, flow meter, and pump. To access this feature from the Main Menu, navigate to
POCs
and
select
Flow Meter and Master Valves
. The Flow Meters and Master Valves screen displays.
Configuring a Traditional POC
A traditional POC consists of a single flow sensor, master valve, and or pump. If this controller utilizes a
bypass manifold, see Configuring a Bypass Manifold instead.
