Use

Doppler flow switch is a material flow detector using the Doppler effect. According to the Doppler effects, the frequency of microwave changes when encountering a moving object. The detector is installed outside the pipeline or above the conveyor belt. The detector emits electromagnetic waves. When there is material flowing, the frequency of the reflected wave changes. When there is no material flowing or blocking, the frequency of the reflected wave won’t change. The detector judges whether the material flows according to whether the frequency of the reflected wave changes and outputs a signal through a relay. The sensor has sensitivity and relay delay settings to avoid false alarms.

Function

This operating instruction contains all the information that is needed in various phase of the life circle of the device: product identification, transport, storage, mounting, connection, operation, setup, instruction for maintenance, fault rectification, exchange of parts, disposal. Please read this information before putting the instrument into operation.

Mounting and Installation

Installation of a FLOWguard 310

(1) The sensor should be installed in a low vibration environment.
(2) No moving parts in the detection area. If this is unavoidable, it is strongly recommended to shield the moving parts.
(3) For horizontal or inclined installation situations, installation from above is recommended.
(4) An installation angle to the flow direction between 45 ~90 should be maintained.
(5) When used on delivery lines made of non-conductive material, the measurement is made through the wall. There is no need for a separate recess in the line.
