Fluidwell F074 Safe Area Level Controller is a basic level/pump controller that works with a preset value and two switch points to control a pump or valve. The low and high-level switch points are entered as a percentage of the preset value to switch the device on / off. For pump control applications, the function can be inverted to empty a well. A stable level within a hysteresis around the preset value is the result. The configuration of the Span, offset and a number of decimals are done through software functions, without any sensitive DIP switches or trimmers. The display shows the actual level, preset value, high/low switch points, and status. On-screen engineering units are easily configured from a comprehensive selection.

Applications

Basic on / off level control applications without PI(D) control requirements. Also very suitable for applications where the required level changes frequently.
Functions for filling-up a container or emptying a well or tank.
The F-Series is your first and best choice for field mount indicators in safe and hazardous area applications. Especially in harsh weather conditions like rain, snow, sandy deserts, salty atmospheres and temperatures between -40°C up to +80°C (-40°F up to 176°F).
