User Guide | Liquid level controller, EKE 347

DKRCI.PD.RP0.A4.02 | 3

Application examples

Pump reservoir

Modulating control of injection for a more stable liquid level and suction pressure.

Separator on flooded evaporator

Modulating control and the valve’s large capacity range ensure a stable level - even under conditions

of quickly changing loads.

Intermediate cooler

The level transmitter’s wide measuring range enables it to monitor the liquid at all levels of the

reservoir - and hence to use the signal for safety functions in connection with the max. permissible

level

Receiver / condenser

The control system’s short reaction time makes it very suited for high-pressure float systems with

small refrigerant charges.
