OPTIBATCH 4011

The OPTIBATCH 4011 is the standard Coriolis mass flowmeter for process batching of conductive and non-conductive liquids. It is a highly accurate and specialised meter for linear and rotating filling machines. The fully welded maintenance-free device with twin U-shape is particularly suitable for hygienic applications in the pharmaceutical or food and beverage industries. It can be equipped with DIN11864-2 hygienic flange connections, hygienic clamp connections or many other bespoke fittings according to customer specifications.

The OPTIBATCH 4011 does not require a separate converter due to its integrated electronics. The flowmeter can be connected to a PLC or DCS via the simple Modbus interface. This allows programming, commissioning and measurement over a single data connection.

Product features and options depend on device configuration: Contact us to make sure that your preferred functionality can be combined in one device.
