Dual
Water and Top Up Systems for Rainwater Tanks |
|
Electronic based dual water or top up system |
 |
|
AQUAMETA is ideally suited as a controller for
regulating the topping up of rain water tanks from mains
supply. This can be a full flow system or a trickle feed system.
This system sets out to maintain a minimum water level in the
rainwater tank for use while reserving the rest of the tank
capacity for rain water.
Enhance water usage management by using
the R1 or R5 wireless water level gauge. |

RainAid float based dual water or top up system |
 |
|
RainAid is
a float based dual water system and is used to top up
rainwater tanks from mains supply. The system does not
require any electrical power. The weighted float can be
set at any height and used as a full flow or trickle
feed system. RainAid is WaterMark approved so it can be
used in any potable water storage application.
RainAid can be used in conjunction with any of our range
of level indicators or gauges.

Water
Tank Level Control using Pumps and Valves |
|
Electronic |
 |
|
|
The AQUAMETA T434R Tank Unit can be
used as a stand-alone control system to control the
action of pumps, valves and other devices. Level
monitoring can be added by combining the T434R with the R1 or R5 level indicators.
Logging or data capture of water levels can be
accomplished by using a RS232 interface connected to the
Tank Unit, R5 or R1 wireless level indicators.
The T434R Tank Unit has a dual pole relay with contacts rated to 10A
that can be used to control voltages to 24V. The relay will energize
when the water level reaches the Low Level trigger point and
de-energize when the water level reaches the High Level trigger
point.
These trigger points are set using dials in the Tank Unit. |

Reservoir valves for large pump fed
tanks - high flow rates required |
|
High flow rate dual level float
valve |
|
High flow rate single arm
reservoir valve |
|
 |
|
Ideal for large pump fed tanks.
Delivers flow rates up to
500 Liters per minute at
300kPa. Accommodates up
to 270mm change in level before activating, minimizing
pump overload and saving on running costs.
This dual valve with its lightweight construction makes
it ideal for plastic walled tanks.
Full flow ensures fast and efficient fill rate. It
features a dual level adjustable setting that allows
multiple draw-off before activating the pump.
The draw-off is adjustable from 65mm to 270mm.

This reservoir valve is ideal for applications
where a high flow rate is required. Typically
used in large tanks and reservoirs. This valve
is capable of delivering 630 Liters per minute
at 300KPa. Maximum pressure is 550kPa(80psi)
with one float or 850kPa(120psi) with two
floats.
Available with 32mm, 40mm and 50mm inlets.

We stock a wide range of high
quality float switches. The
range includes float switches
suitable for directly switching
pumps and valves as well as
float switches suitable for
providing control signals to
PLC's, relays and control
panels.

We stock
water level alarm systems that generate visual and
audible alarms. A new system that will dial out on a
standard telephone line has just been developed. This
system can dial up to 5 numbers and play a pre-recorded
message in the event of a level alarm. |

How does the AQUAMETA work ?
AQUAMETA uses a
differential pressure sensor, suspended into the water tank.
This pressure sensor measures the depth of water in the water tank. The
deeper the water, the higher the pressure reading.
This pressure sensor
is connected to the AQUAMETA Tank Unit. The Tank Unit is installed on the top of
the water tank. At time of installation the Tank Unit is calibrated
using a dial in the Tank Unit so that it knows the maximum water depth
to monitor. Using this technique ensures
that a reading, accurate to within a couple of mm, can be achieved.
When measuring the level of water in the tank, the Tank Unit takes a pressure reading.
This pressure reading is converted and compared to the maximum
depth. A % reading is calculated and then transmitted to the
AQUAMETA display unit which can be located up to 300m
away
(line
of sight). The water level is displayed
on a 10 element
LED bar graph.
AQUAMETA can be set to take readings every 6 seconds to
once every 30 minutes. This means that you can set how
often your water level is updated on the display gauge. |
|
How does Rain Alert Work ?
Rain Alert is installed on top of the water tank and
uses a ultrasonic sound beam to sense how far the water
surface is from it. The vertical height from the sensor
on top of the tank to the bottom of the water tank is
set on the Rain Alert display at time of
installation. This is accomplished by setting switches on the back
of the display unit. The depth of the water tank can be set in
increments of 50mm.
Once every hour, the Rain Alert transmitter senses the level of the
water in the tank by sending out a beam of ultrasonic sound. The
sound is reflected from the water surface and is detected by the
Rain Alert transmitter. The transmitter measures the time it takes
for the sound to travel to the water surface and back again. The
lower the water level, the longer it takes the sound to travel.
This measurement is then transmitted to the Rain Alert Display unit
which can be located up to 200m away (line
of sight). The Display Unit then
displays the water tank level on a 10 element LCD bar graph. |
