Electromagnetic large flow meter
- with local display

The robust and reliable MIDEX large flow meters provide cost-effective flow measurement with high measurement accuracy under different process conditions in underground mining. The flow meter is used to measure the flow of electrically conductive liquids such as water, emulsions, sludges, pulps and pastes. The devices can be used in large refrigeration plants to measure the flow of fresh and mine water, as well as hydraulic fluids, and to monitor hydraulic mine-waste delivery, for example. The transmitters are wear- and maintenance-free as they do not have any moving parts.

The large flowrate measuring device is available with different nominal diameters from DN50 to DN300 (also with high-pressure couplings, e.g. SSKV heavy series, available as an option), as well as nominal pressure ranges from 10 bar (1 MPa) to 500 bar (50 MPa). The measuring range can be freely programmed within specific ranges if requested by the customer. The large flowmeter can be supplied with all electrical connections that are commonly found in underground mining and has up to eight programmable outputs (5-15 Hz frequency, impulse, limit value [switch point and switch behavior freely programmable], flow direction, medium detection).

Another feature is the digital local display with status display of the potential-free optocoupler outputs.

• Robust and reliable at different process conditions
