Foam Detection & Control Systems

SureSense+ Foam Detection System

The SureSense+ range is designed to enable the accurate control of aqueous foam by sensing when foam touches the end of the probe. SureSense+ systems have excellent resistance to fouling/build up and will still operate reliably with even the largest deposits on their sensing elements. SureSense+ units can can work with up to three sensing points in total, either on the same probe on from probes in up to three separate vessels, and are used extensively for controlling and ultimately reducing the consumption of chemical antifoam agents across a wide variety of processes and industries. Each unit has five relay outputs configurable for foam detection, dosing control, high level indication and liquid level detection. A 4-20mA output is included to indicate foam quantity. Sensing probes can be mounted horizontally or vertically.

SureSense+ Foam Sensors

SureSense+ sensors are built to use Hycontrol’s patented IMA Sensing® technology that provides reliable detection of foam, even when coated or fouled with process material. SureSense+ sensors are available with one, two or three sensing points to suit individual process requirements. Mounting is simplified by the wide variety of process connection types available and process compatibility served through different wetted material types. Sensors can be customized for length and shaft diameter or supplied so they can be adjusted in-situ. Hygenic SureSense+ sensors are steam sterilizable and/or autoclavable.

SureSense+ Foam Controller

The SureSense+ controller utilizes unique IMA Sensing technology to ensure reliable operation even in the presence of severe sensor fouling. To discriminate between the continuous presence of foam and splashing or other spurious triggers, there is an adjustable response time function. When foam is detected, one of three user selectable control methods – off/on dosing, shot and delay dosing or Proportional/Integral control – can be used to trigger operation of a pump or valve to start anti-foam chemical addition. Liquid level can also be detected and reported as a status output.

Units can be connected to supervisory control systems/other control elements to enable foam control using vacuum valve setting or gas flow regulation. Volt free contacts can be used for point detection, alarm status or to control dosing pumps/valves directly. An analog output is available for amount of foam present indication. The display on the controller provides at-a-glance status of all inputs and outputs.
