Overview

The Toro ﬂ ow sensors provide an accurate ﬂ ow measurements by generating a frequency signal (pulses per second)

that is proportional to the ﬂ ow rate. The Toro ﬂ ow sensors are designed for below grade applications for irrigation

monitoring where the ﬂ ow rates are between 0.5–30 ft/sec and temperatures are below 180º Fahrenheit. The

Toro ﬂ ow sensors are supplied with two single conductor, 18 AWG solid copper wire leads with U.L. Style 116666

direct burial insulation. An internal preampliﬁ er allows the pulse signal to travel up to 2000’ without further signal

ampliﬁ cation.

Controller Compatibility

The Toro ﬂ ow sensors are compatible with the following controllers:

• Toro TMC-424 • Toro Intelli-Sense

TIS-360/480

• Toro Sentinel

• Toro SitePro

• Irritrol MC-E • Any controller compatible with Frequency output ﬂ ow sensor

(Pulse per Second proportional to ﬂ ow velocity)

Sizing

The following table indicates the suggested ﬂ ow range of the Toro ﬂ ow sensors. Although the sensors will operate

above and below the indicated ﬂ ow rates, following the suggested range will ensure the best performance from the

ﬂ ow sensor. Sensors should be sized according to ﬂ ow rates rather than pipe size.

Flow Sensor to Pipeline Installation The accuracy of the flow sensor’s measurement is highly dependent on proper sensor location within the piping system. Irregular flow velocity caused by valves, fittings, pipe bends, etc. can lead to inaccurate flow rate measurements even though local flow velocity measurements may be accurate. A sensor located in the pipe where it can be affected by air bubbles, floating debris, or sediment may not achieve full accuracy and could be damaged.

Cable Installation Step 1 - Use a twisted pair cable suitable for direct burial to connect the sensor to the controller. Multi-pair telecommunication cable or direct burial cables may be used. Shielded cable is recommended. Connect the cable wires to the sensor wires. TSM-4F Module Example: Sensor Connection to TMC-424 Step 2 - Waterproof the splices. Two part epoxy waterproofing kits or waterproof wire connectors are recommended. Step 3 - Route the cable from the sensor to the controller.
