Flow Guard M
Flow Switch for solids in free fall, sliding or conveyed systems
- FLOWguard M uses Microwave Technology
- Easy installation and start-up
- Integral solids flow switch with a relay output for Flow/ No Flow Alarm
- Detection of moving material only – no influence from deposits
- Long-term stable, reliable, robust and repeatable
- Stainless Steel 1.4305 (AISI 303) housing
- General Purpose or EX versions
The FLOWguard M microwave flow monitor is used to detect the movement of solids in open and closed conveyor systems, whereby large distances to the conveyed goods are also possible. Irrespective of the direction of movement, bulk materials that move through the detection area at a minimum speed of 0.1 m/s are detected. Malfunctions in conveying systems for powder, granules, pellets and other bulk materials are detected at an early stage and thus avoided. This helps prevent equipment failures such as clogged lines, wasted material, idling, or other serious problems.
FLOWguard M is installed at an angle of 45° to 90° to the flow direction. Moving mechanical devices such as rotary valves, propellers or similar must not be in the detection area, as they would be interpreted as moving bulk material. If these ‘interference sources’ cannot be relocated, they must be shielded or a FLOWguard based on the electrostatic principle such as FLOWguard P should be used.

Use
The flow switch FLOWguard M is used for monitoring the mass flow in open and closed transport processes.
Independent of particle moving direction solid materials with velocity of at least 0.1 m/s in the detection field will be
detected.
Function
The FLOWguard M measuring system is intended to measure material in a microwave-impenetrable material, or to measure a microwave-penetrable material in closed systems or systems isolated from waves.
The measuring system is one which transmits directed electromagnetic waves and receives the reflections. To limit the wavelength to the required frequency band, ensure the sensor is only operated within the approved temperature range.
The sensor features a standby and signal output. The signal output is provided as a changeover contact. The outputs are designed as control outputs. Therefore it is not allowed to use voltages and currents higher than those specified in the technical data.
Mounting and Installation
The FLOWguard M has to be installed with an angle of 45° to 90° of flow direction. Moving mechanical parts e.g. rotary valves, screw conveyors, or similar should not be in the detection field because they might be detected as flow of material. If these parts are not
avoidable, they have to be shielded or a different flow switch has to be used.
