Simple Complete Control

The Sure Level 500 is a multi-level sensing water level controller designed for any swimming pool or spa. The days of setting probes or floats at the exact desired heights are gone. All levels – High, Low, Normal Operation – are easily set and controlled electronically through the microprocessor controller. The controller utilizes one hydrostatic pressure transmitter that is maintenance free and accurate no matter the size of the body of water it is controlling. The controller can be preprogrammed at the factory to suit any application or programmed on site in a matter of minutes. Easy interlocking of the controller will prevent overflowing the system – even when the “Manual Fill Valve” has been opened – and prevent pump cavitation when the water level drops below the low limit set point.

Reliable Maintenance Free Sensor

The Sure Level 500 utilizes state of the art hydrostatic pressure technology to provide the most accurate depth readings in real time. The submersible level transmitter is constructed of durable 316 stainless steel combined with a ported polyoxymethylene nose cap to ensure reliability and a long lifespan. The over-molded shielded cable used to connect the sensor to the controller is designed to protect the signal wiring and atmospheric vent during installation in conduit or in an open-air wiring design as well as shield the signal from any electrical noise interference. The sensor can be installed in the lowest point of a surge tank, stand pipe, or sight well and then programmed through the microprocessor controller. No more hassles of getting multiple probes or floats set at exactly the right level.

High and Low Water Level Protection

The Sure Level 500 also functions as failsafe protection for filters and pumps. No more burned out pump seals and returning media to the pool due to pump cavitation. When a low water level is detected a signal is sent to shut down the circulation system before any damage can occur to the equipment and prevent cloudy water due to media release in a regenerative media filtration system. High water level detection prevents overflowing the system by closing a failsafe solenoid and avoiding any damage to the pool mechanical room, natatorium, and surrounding areas such as gyms and exercise rooms that have expensive equipment and flooring.

Product Highlights

The Sure Level 600 is an extremely precise and reliable multi-stage water level controller, and electronic main drain valve controller. The Sure Level 600 is specially designed for bodies of water that incorporate an external surge tank, or balance tank in the system. The controller automatically monitors and controls the water level in the surge tank, and controls an electric valve on the systems main drain line.

The Sure Level 600 water level controller utilizes hydrostatic pressure transmitter technology to convert water pressure to level. The controller’s large numeric readout, and indicator lights enable operators to easily verify proper operation, and level with a simple visual scan. The Sure Level 600 monitors and controls normal, low and highwater levels with one hydrostatic pressure level transmitter. That same transmitter signal is also used to control the operation of the electronic main drain modulating valve. This transmitter can be installed in a surge tank, stand pipe, or sight well. The sensor gets placed in the lowest point of whatever installation method is used. The actual levels are programmed using the microprocessor controller. No hassles of getting multiple probes or floats at exactly the right level!

The plc controller input is a 4-20ma signal from the level probe. The controller has four programmable relay outputs, and one programmable 4-20ma output. The four relay outputs are configured for normal water, low water level, high water level, and Alarm. The 4-20 ma output signal controls the main drain valve.

Main Drain Valve Control

The programmable 4-20 ma output signal uses water level and converts it to a milliamp signal. This signal is used to proportionally control an electronic valve actuator connected to a butterfly valve. This replaces the mechanically float controlled modulating valve. Now the pool level, and the surge tank level can be the same. No more worry about water equalizing, and running out the overflow. A battery backup system on the valve actuator assures this control, even in the event of a power outage.

Water Level Control

Normal water level settings control a fill solenoid to maintain precise water level down to less than an eighth of an inch. Low water settings can be configured to interlock with your circulation system to prevent pump low water condition. High water level settings control a shut off solenoid to prevent over filling from a malfunction or someone forgetting to shut off the manual fill valve. An alarm, or aux output available for audible alarm, light, etc.
