Operation
Put the Bypass Switch in the “Auto” position for 
normal sensor control of the system. Putting the switch 
in “Bypass” position closes the circuit to the solenoid 
valves independent of the rain sensor switching.
Sensor Guard
Vandal resistance and rain sensor all-in-one
Combining the reliability of a Mini-Clik
®
 rain sensor 
with the security of a compact vandal resistant enclo-
sure, the Sensor Guard is perfect for sports facilities, 
golf courses and municipal sites. Easy to install, the 
Sensor Guard includes a Mini-Clik 
conduit rain sensor plus stainless 
steel mounting bolts and a drill tem-
plate. A great way to keeps hands 
off the Mini-Clik when mounting 
the unit on pedestal controllers or 
controller enclosures.

FLOW-CLIK™ 
FLOW SENSOR
Affordable, Rugged and Reliable Flow 
Monitoring System
Shutting down an irrigation system when excess 
flow occurs provides the benefits of reduced liability, 
water conservation, erosion prevention and an overall 
reduction in repair costs. Typical causes for over-flow 
conditions can stem from problems due to ruptures 
in the main or lateral lines, when heads are broken or 
removed from the system, or valves do not shut off au-
tomatically. Until now, installing a flow sensing device 
as an integral part of the irrigation system on many 
sites was cost prohibitive due to the relatively high cost 
of the flow sensing device itself as well as the Central 
Control system needed to monitor them. 
The new Hunter Flow-Clik
®
, is a sophisticated flow 
sensor that monitors flow to an irrigation system. In 
the case of an overflow condition, the Flow-Clik will 
automatically shut down the irrigation system. 
The Flow-Clik acts as a switch to break the electri-
cal circuit to the solenoid valves as soon as it registers 
a flow exceeding a calibrated set limit. This allows the 
timer to advance as scheduled, but keeps the valve(s) 
with a “high flow” from activating.
As a result of installing the flow sensor in a system, 
a user gains the benefit of substantially reducing the 
amount of water loss during an occurrence of an over-
flow situation.
PRODUCT FEATURES 
AND BENEFITS
Low Cost…
An extremely reliable and accurate flow sensor for 
any system budget
Unlike other flow-sensing devices by other manu-
facturers and the central control systems needed to 
receive the benefits of monitoring flow are very costly, 
the relative low cost of the Hunter Flow-Clik fits into 
any site's budget. At a fraction of the cost, the Hunter 
Flow-Clik provides the many benefits associated with 
monitoring flow. It will work with all Hunter control-
lers as well as many other manufacturer controllers. 
The Flow-Clik is the perfect choice for any contractor 
or property owner who is interested in monitoring flow 
to reduce their exposure to liability, reduce repair costs 
and conserve water.
Liability Reduction…
Minimize the possibility of litigation from 
unforeseen system breaks
Today, the reality of lawsuits is a real concern to in-
stallers and property owners alike. They cannot ignore 
any hazardous situation that can be easily prevented, 
including an event such as an irrigation system that has 
excess flow due to a ruptured mainline pipe or a dam-
aged sprinkler head. This excess water flow may cause 
flooding onto an area that can pose a danger of injury 
to the public making the risks of a potential lawsuit 
very real. The costs associated with this potential li-
ability can be huge. Installing a Hunter Flow-Clik™ as 
an insurance policy will pay dividends in dollars and 
“peace-of-mind”.
