Rev. 1a, 2/03 ACF-10 Series

• Introduction

The ACF-10 Acoustical Flow Sensor is a compact unit that detects audible

noise made by powders and grains which is converted to a relay output.

In addition, since the ACF-10 is attached to the outside of the pipe or chute
and does not contact directly with the grains to be detected, the ACF-10 will
not have critical problems of flow fluctuations caused by conventional contact­type sensor inside the pipes and chutes, and with abrasion and corrosion
problems of the contact-type sensor. The ACF-10 can be easily attached to
existing pipes with straps.

The ACF-10 is easily adjusted with the use of four LED.
