Advanced Foam Controller For Food And Chemical Manufacturing

Charis Technology is now distributing the FCW2 advanced Foam Controller for use with the company's Foam Sensors to control the foam in processes including biotechnology, food and chemical manufacturing.

The new Controller uses Charis Technology's IMA Sensing technology to sense and control foam at a fixed level or to reduce it to a minimum. Considerable reduction in antifoam use can be achieved, according to the company.

The FCW2 will operate correctly even in the presence of severe fouling of the sensor, says Charis. The controller can be used for ‘stand-alone' control for foam or can be interfaced to a process controller.

An adjustable response time discriminates between foam and splashing or other spurious triggers, while a dosing or shot time can be set for the operation of a pump or valve for antifoam addition.

Other control actions such as vacuum valves or gas control can be interfaced, and volt-free contacts can be used for point detection and an analogue o/p for level indication.

The FCW2 has been designed specifically for foam and is not a modified liquid level controller.
