![display unit operation
The meter is equipped with two external
buttons on the electronics housing side
and three internal buttons accessible
after removing the front cover with glass.
Using the external buttons, it is possible
to scroll individual quantities and settings.
After removing the cover, it is possible
to change settings as well.
The unit can be swivelled within 350°
for more comfortable reading of values
on the display both in compact and
separated designs.

- 1. FLOW 38 INDUSTRIAL FLOW METER MAIN MERITS • Extensive variability of process connection • Possibility of the constructional length made to customer needs • Possibility of the sensor made in full stainless steel design • Big dynamic measuring range • High measurement accuracy and repeatability • Wide choice of materials for liners and electrodes • Very simple and intuitive operation • Possibility of flow monitoring function (flow switch) • 350° swivel display for comfortable reading Industrial inductive flow meter with display unit. The flow meter is designed for a wide range of fluid measurements in various industries. Various process connections such as flange, sandwich (wafle), threaded and dairy fittings (DIN 11851) or clamp types are available. The evaluation unit is made in three versions. It includes the standard design (head) and the unit is also made in front and panel designs. It is advantageous in the compact front version that the evaluation unit (display unit) is placed from the front part of the sensor and in case of the separated version, the display unit can be mounted in DIN rail. The panel mounted electronics offers the installation of the display unit in the electric box door. The flow meter offers a wide range of outputs and the communication for connection to various control systems.
