ORDERING INFORMATION
WATER SENSOR / SWITCHAQS00660, AQS00661, LD1-24
DESCRIPTION
The Model LD1-24 and the AQS models are small electronic control relays for detecting a rising water level . Inside a waterproof enclosure, each model features a medium-power relay, which is operated by water reaching the trip level, and can be used to control alarms or other equipment . The relay is normally energized when the power supply is switched on and no water is present . When water rises up the side of the box to reach the switching level, the relay drops out . This sequence is failsafe, allowing each model to be used as a water spillage alarm switch or to turn off a valve or an air conditioning unit before the water overflows its containment .
FEATURES
• All components safely encapsulated against moisture ingress
• Switching capability 5A at 240 VAC

CABLE-STYLE WATER DETECTORLD310 SERIES
ORDERING INFORMATION
DESCRIPTIONThe RLE Technologies LD310 cable-style water detector reports the presence of water within a predetermined zone . The LD310 is a single zone system with both a visual and audible alarm indicator as well as a separate output relay for leaks and fault detection .
The LD310 continuously monitors leak sensing cable and is ideal for small areas . If conductive fluid contacts the sensing cable anywhere along its length, the module will activate a leak relay and audible alert, and flash the LED, clearly indicating fluid has been detected . If the sensing cable is cut or comes loose, the module will activate a cable fault by flashing the LED and activating a fault relay .
The LD310 also features three jumper selectable leak detection thresholds for adjusting the sensitivity of the leak/fault detection circuit .
FEATURES• Dual dry contacts alarm fluid or fault detection• Three adjustable alarm thresholds• Bi-color LED indication for normal/alarm conditions• Audible alert that is jumper selectable on/off • Push-button switch allows users to test and reset the
system and silence audible alarm

DESCRIPTIONThe Waterline Controls WLC Series electronic water level control system may look like the competition but the unit is revolutionary in its design . The WLC Series is perfect in any application where water level management is important such as cooling tower basins and water holding tanks for cooling towers . It uses a microprocessor that monitors all probes for correct operation and then provides the corresponding outputs to drive the power relays, the Building Automation System and a visual indication of the operational status . The Modular construction and a self-test feature insure user-friendly operation . By using a very low voltage and current, WLC Series sensors never foul or degrade . So when we say "Never Replace A Water Level Controller Again" we mean it!
FEATURES• Easy installation• Simple, reliable, and automatic• Compensates for wave action• No moving parts or mechanical floats• Liquid tight enclosure• Accurately manages levels to within 1/8" of operating
range• Easy to read LED display

LIQUID LEVEL MEASUREMENT
One of the features of the M230 that makes it ideal for liquid level applications is the wide variety of ranges available . Assume you want to monitor a water level of 0-60” in a vented tank . To select the correct range for the M230, simply convert the 60” W .C . to psid .
60" W .C . = 5' W .C . 5 ft = 2 .16 psid 2 .31 ft/psid
The M230 is available in many standard ranges . The best selection for an application measuring 0-2 .16 psid is the M230-005PD-C with a standard range of 0-5 psid . Assume a cooling
tower with a 3’ deep sump is mounted on a roof, and a M230 used to monitor the level is in an equipment room on the top floor (see Figure 3) .
The pressure at the M230 when the sump is full is 3 ft + 10 ft = 5 .6 psid 2 .31
Of this 5 .6 psid, the pressure caused by the water in the cooling tower sump is 3 ft = 1 .3 psid 2 .31 The remaining 4 .3 psid is created by the water in the tube between the M230 and the bottom of the sump .
An M230-010PD-C (0-10 psid range) would be the proper transmitter .
When using pressure transmitters for l iquid- level measurement, the following precautions should be taken:1 . Verify that the pressure transmitter is compatible with the
liquid being monitored . 2 . Protect the pressure transmitter from freezing and over-
temperature .3 . To protect the pressure transmitter from rust, scale,
sand, etc ., do not connect the sensing tube to the low point of the sump . Either connect into the side of the tank, or insert the sensing tube into the bottom of the tank so the tip of the tube is slightly above the bottom of the sump .
4 . When used on pressurized systems, be sure that the system pressure plus the liquid pressure does not exceed the static pressure rating of the differential pressure transmitter .
If you have any questions, please call Kele .

LIQUID LEVEL MEASUREMENT
The Bubbler SystemOne of the most difficult applications frequently encountered in the building automation industry involves measuring the level of liquid in a tank . The Bubbler System is one solution for continuously measuring liquid level . This system involves forcing a stream of compressed air through a tube that is inserted into a tank . The pressure required to force the air out of the tube is equal to the pressure created by the liquid above the end of the tube . By measuring this pressure, the level in the tank may be determined .
Using a Pressure TransmitterA simpler method of measuring liquid level is to install a pressure transmitter level with the bottom of the tank or at the lowest level that must be monitored . If the specific gravity of the liquid in the tank is known, then the liquid level may be easily calculated . The Model M230 differential pressure transmitter is excellent for this application .
Remember, the water height, or “L” (see Figure 2), is measured from the low port of the pressure transmitter to the top of the water level .
When used on a vented (non-pressurized) tank, the high-pressure port is piped to the liquid at the bottom of the tank, and the low-pressure port is vented to the atmosphere . The M230 then measures the pressure created by the liquid (see Figure 1) . This method may also be used to measure liquid level in a pressurized tank by piping the low-pressure port to the top of the tank above the liquid . The M230 will then measure the difference in pressure created by the liquid in the tank (see Figure 2) .
Now that we know the pressure created by the liquid in the tank, how can we convert this to liquid level? Due to gravity, a column of water at 70°F, 2 .31’ high creates a pressure of 1 psig . Therefore, if the liquid in the tank is water, multiplying the pressure indicated by the M230 by 2 .31 will provide the level of water in the tank in feet . As shown in Table 1, the value of 2 .31 ft/psid is relatively accurate for the temperature of water in most HVAC processes . If the temperature of water being monitored is known, the value for ft/psid corresponding to the water temperature in Table 1 may be used in place of 2 .31 .
For example, assume the tank in Figure 1 contains 100°F water . The M230-002PD-C has a range of 0-2 psid (4 mA output at zero pressure and 20 mA at 2 psid) . If the output from the M230 is 17 .8 mA, what is the water level?
