The Drumline WLS (Water Level Switch) is a solid state electronic unit that is designed to sense the presence or absence of water in a variety of pressure and temperature applications. The unit is predominately aimed at the power generation, petrochemical, refinery and manufacturing industries.
The Drumline WLS is based on the principles of conductivity and utilises conductivity probes as the sensing element. The design is modular; therefore, you only purchase the number of channels you require. Each channel is independent and can be set up according to requirements.
The DLWLS consists of a motherboard that can take 1 to 4 daughter boards. Each daughter board is one independent channel, 2 built in SMPS power supplies power the complete unit. A local LED display is provided for a visual indication for steam, water and alarm. Each daughter board features, adjustable relay delay settings, selectable sensitivity, relay normally energised in steam or water, 2 amp rated DPDT relay.
The motherboard supports a remote display through the peripheral connection and a 16 core cable. The peripheral connection allows for the development of custom addons such as remote relay boards.
OPERATIONEach channel is set via a jumper to a normal operating state, either steam or water. When the unit senses that the probe is not in its normal state, the Alarm LED is illuminated.
LOCAL DISPLAYAs with all the DLWLS series electronic level switches. The local display is detachable. This means that it can be mounted remotely from the electronic unit, providing a more convenient visual indication. The display provides a green LED to indicate water, a red LED to indicate steam and a flashing amber LED to indicate that the probe is sensing a state different from the set default mode.

RELAY TIME DELAYEach relay has an adjustable time delay of 0-10 seconds. The delay occurs when a channel switches from normal operating state to alarm state, this helps combat spurious alarms due to water splatter etc. The delay time continually resets until the full time elapses without a change in state.
Each relay is rated to 2 amps and are Double Pole Double Throw.
SENSITIVITYEach channel can have the sensitivity set via DIP switches. Settings are available for 2 micro siemens and above, 1 micro siemens, 0.5 micro siemens, 0.3 micro siemens. There is also the ability for custom factory settings.
PROBE CONNECTIONEach channel can use 2 or 4 wire connections, only 2 are required. 4 wires are used for extra redundancy.
