ABSTRACT

Many types of solids flowmeters are currently available. The majority use some method of weighing, while others utilize a variety of other phenomena, from radiation to impact force determination and from electrical properties to centrifugal force. This chapter covers them all except Triboflow switches and cross-correlation flowmeters. The bin, the feeder, and the solids flowmeter should be designed in an integrated manner, taking into account the characteristics density, particle size, moisture content, temperature, or hazardous properties of the solids. A number of common materials, of which sulfur is an example, will compact unless kept in almost continuous motion, and in some instances will compact even while in motion under the pressure of a relatively low head of material. All manufacturers recommend that a feeder or meter be isolated from sources of vibration, and some include shock mounts with each machine.
