DCM Drainage Control Monitor

Water-level detectors, sometimes referred to as floats, often fail due to the hostility of the environment that they are installed in. Ultrasonic sensors are also prone to inaccuracy as they can become confused by foaming in submersible pits. The DCM overcomes these problems by using the pump motor as its own load sensor. The DCM uses an algorithm to automatically calculate an appropriate pump pause time based on an average of previous run times to continuously adjust pump operation to suit the pit filling rate.

No Maintenance Costs

Unlike water-level detectors, which often demand constant attention, DCM units are highly reliable electronic devices that are maintenance-free and are protected in a cabinet.

Automatic Pump Control

When the submersible pump begins to draw air because of a lack of water in the pit, the DCM detects the resulting lower motor load. When the preset underload limit is exceeded, the monitor stops the pump.

As the unit continuously monitors the pump running time, the period just elapsed is used to determine the time of the following pause period. The longer the run period, the shorter the pause period. Thus, pump operation varies automatically according to the pit filling rate.

Lower Installation Costs

The DCM eliminates the need for at least 3 water-level detectors: low-level, high-level for one pump and high-level for two pumps. Thus, significant cost-savings result from dramatically reduced purchasing and cleaning of detectors.

The DCM system is also more secure because it uses the pump motor as its own load sensor, whereas detectors often fail because of the effects of the environment in which they are installed.
