Application
The combination of a straight sensor tube with zero dead volume, self-drainability and hygienic connections, makes the ES-
FLOW especially suitable for hygienic applications. Examples of typical use are the measuring of food ingredients like
flavourings or syrups, or measuring concentrates in CIP units. For non-hygienic applications, the instrument can be
equipped with compression type fittings. Wetted parts are made of stainless steel, the housing has a high ingress
protection rating.
Operation
The
ES-FLOW™
can be operated with the integrated readout and control unit, as well as digitally, via RS-232 or fieldbus
(Modbus, FLOW-BUS, PROFIBUS DP, PROFINET, DeviceNet™ or CANopen®), or in analog mode. The readout and control unit
has a capacitive touchscreen with a TFT display. The fluid temperature can be read out as a secondary output. An on-board
PID controller can be used to drive a control valve or pump, establishing a complete, compact control loop.
By default, the instrument is supplied with the readout and control unit above the measuring tube (assuming the flow
direction is to the right). If so required, the flow direction and display orientation can be customized to support a
convenient reading angle. The illustrations in this manual are based on the default orientation.
Multi-range
The
ES-FLOW™
offers multi-range functionality: factory calibrated ranges can be re-ranged to a different full scale range.
Because of the extremely high linearity of the sensor, this does not affect the original accuracy specifications.
The instrument comes with a calibration certificate for all supported full scale ranges. The actual full scale of the instrument
is set to a value as ordered.
