Electromechanical level meter
- Measuring range up to 110 m

The FMM50 is an electromechanical level meter with a measuring range of up to 110 m. Depending on the selected sensing weight, the level can be measured in bunkers or silos containing dusty, fine-grain or coarse-grain bulk solids or in tanks containing liquids, independently of the product characteristics. Depending on the mechanical design and equipment, it is possible to take measurements in silos or tanks with operating temperatures up to 230 °C, with a process pressure up to 3 bar (absolute) or with aggressive atmospheres, e.g. acidic or alkali steams.

• Building materials, rocks and earths
• Wood industry
• Foodstuffs, animal feed
• Chemical industry
• Metal industry
• Power plants

• Simple, secure and readily understandable measuring principle, technique is known in almost all industrialized countries
• Easy to use, excellent price / performance ratio
• Accuracy of ±5 cm or ±1 pulse, therefore precise detection of the level
• Compact device, with 0/4-20 mA current output and other freely programmable signal outputs (e.g. counting pulse, reset pulse, maintenance, run-up, upper limit position, alarm, measuring active)
• Simple menu-guided onsite operation with four-line plain text display
• Fully electronic digital minimum fail-safe control, therefore no running down of the sensor weight into the silo outlet and no risk to the conveying systems
• High performance three-phase engine (traction power up to 500N) using a single-phase supply voltage by employment of a converter, therefore simple electric supply
• Optional design with certification for application in areas subject to dust explosion hazard
• Suitable for interface applications
