This paper discussed the electrostatic sensors that have been constructed for real–time mass flow rate measurement of particle conveying in a Pneumatic pipeline. Many industrial processes require continuous, smooth, and consistent delivery of solids materials with a high accuracy of controlled flow rate. This requirement can only be achieved by installing a proper measurement system. Electrostatic sensor offers the most inexpensive and simplest means of measuring solids flows in pipes. Key words: Electrostatic sensor, cross-correlation, peripheral velocity

Kertas kerja ini menjelaskan beberapa jenis penggunaan penderia untuk mengukur laju aliran pepejal yang mengalir di penghantar pneumatik. Setiap penderia akan menggunakan prinsip yang berbeza tetapi kebanyakan darinya mampu mencapai kesilapan homogen sebanyak 10%. Teknik–teknik ini termasuk penderia kapasitan, penderia elektrostatik, penderia gelombang mikro, penderia radiologi, kombinasi penderia elektrostatik dan digital imej dan lain–lain. Reka bentuk penderiaan harus seragam, maka zarah yang ada dalam kawasan penderiaan akan memberikan hasil yang sama terhadap isyarat mengalir. Kata kunci: Aliran pepeja; penderia; penghantar pneumatic; kaedah pengukuran This paper describes several types of sensor use in measuring mass flow rate of solids flowing in pneumatic conveyors. Each sensor will applied different principle but most of them are able to achieve 10% homogeneity error. These sensor techniques include capacitance sensor, electrostatic sensor, microwave sensor, radiological sensor, combination of electrostatic and digital imaging sensor and others. The sensing filed designs need to be uniform, thus particles exist within the sensing field will contribute equally to the flow signal.
