Features
The EKE 347 controller is used for regulation of
the liquid level in:
• Pump reservoirs
• Separators
• Intermediate coolers
• Economisers
• Condensers
• Receivers
The controller is communicating with a
transmitter that continuously measures the
liquid level in the actual reservoir.
By comparing the measured value with the
level setpoint entered by the customer, the
controller dictates the valve to increase or de-
crease the liquid flow to or from the reservoir.
