The MFD-4 is a media flow detector for suction-type abrasive blasting machines. The MFD-4 uses a charge-coupled amplifier that is connected to a sensing pin. The pin is inserted into the flow path of the abrasive blasting media. Each particle passing the pin shares a minute charge with the pin. This charge is converted to a voltage that is used to activate an output relay contact.

Setup is simple. The zero and span functions are automatic—pushing the “zero” button acquires zero for the no-flow condition and pushing the “flow” button sets the sensor gain and activates the relay. The relay contact will transfer whenever the flow is 50-100% of the programmed setting.

The MFD-4 is enclosed in a rugged aluminum housing. It can be attached to the media blast hose at any location and in any orientation via a sensing pin that protrudes from the bottom of the mounting base. (A sensing pin is included with the MFD-4. Replacement pins are available from Electronics Inc. See below.)
