Aggregate flow indicator and totalizer is a sophisticated microprocessor based instrument designed to show rate and total of the materials used in mixing plant. It is a rate indicator cum totalizer and can be used to measure flow of any parameters by using proper transducers. 4 digits seven segment for rate indication, 6 digits seven segment for tantalization, 4 nos. membrane keys for SEL, INR, DCR and ACK functions. Analog/high frequency input signal required for indication & tantalization.
