Microwave flow switch

YMF series

A flow sensor which detects the flow or clogging of powder and granulated material in pipes and silos.

This flow meter uses a non-contact method to monitor the flow (or clogging) of powder and granulated material.
It is ideal for detecting the flow of insulating powder and granulated material, as well as powder with a low specific gravity.
The latest technology allows for both a compact form and a high sensitivity.

Since this is a non-contact type sensor, it does not interfere with the flow of powder or granulated material in pipes.
This sensor is highly sensitive and can even detect a single grain of material.

Features, keys

Highly functional, high performance, and compact
Employs the latest technology allowing these units to provide high sensitivity, high precision, and remain compact.
It can detect very small grains of material (a single pellet).
Non contact
Since this is a non-contact type sensor, and the electrode does not protrude into the pipe, it does not interfere with the flow of powder or granulated material.
It is unaffected by dirt or other material stuck to the sensor.
Very strong microwaves permeate through dirt and material stuck to the oscillator surface, they cannot cause faulty detection.
