» Separate Water and Oil
Leak Detection System: RGW Series
RGW Systems are designed to monitor from separate sensors which
can differentiates between oil and water in areas where both
liquids could be present, such as in lift pits, tank rooms, plant
rooms, boiler rooms etc. RGW systems are available in three cabinet sizes: 1 to 8 zones, 1 to 16 zones
and 1 to 32 zones.
RGW System are normally fitted with one RedEye Oil Detection Sensor
and one Water Detection Sensors for each zone. Sensors can be housed
in a common wall mounted housing and are connected to the RGW Unit
by a multicore cable. The RGW unit shown left was one of a series
fitted to individual lift pits where monitoring was required of two
separate levels of rising water and one level of hydraulic oil. I
On the assumption that detection is of oil, then the water sensor
would not be affected by oil as oil is non conductive, but the oil
would be picked up by the RedEye Sensor. Therefore only one LED, the
oil sensor, would be illuminated on the RGW for Zone 1. If detection
is of water, than both sensors would go into alarm, and two LEDs
would be illuminated on the RGW Unit.
The RGW System is provided with individual zone
alarm lights and a mutable horn which come on immediately any
sensor is activated. The sensing and the alarm are immediate and
simultaneous with any other. The Alarm light remains on
while the Sensor remains in contact with the leaking substance. The
system automatically resets when the liquid is cleared, requiring no
operator input.
The RGW MultiZone is provided with a common alarm relay and
optionally with individual zone signalling relays. Relays can be
linked to an Aqualeak Annunciator Alarm, to a BMS system,
or to switch on/off control systems etc. The RGW MultiZone System
can be supplied with optional Battery Backup Pack, and can
be linked to the Aqualeak AutoDial unit. The leader cable
distance between the controller and sensor should not exceed 50m. It
should be noted that as water sensing is carried out via conduction,
the RGW system should not be used with any volatile liquids or
gasses present.
