Type B
The ACU10FM battery-powered flow meter uses multi-parameter measurement technology. One instrument can replace four instruments: differential pressure, pressure, flow, and totalizer, saving customers procurement and installation costs. The integrated flow meter uses full-parameter dynamic compensation technology to improve the instrument's accuracy and rangeability; full-scale static pressure compensation technology improves the accuracy of the flow restriction device operation; it can be calibrated with the flow restriction device integrally, and the calibration accuracy is superior to that of the separate type; the functions are specialized and integrated;
The ACU10FM battery-powered flow meter is equipped with a maintenance-free rechargeable battery that can work continuously for more than one year without external power supply. It is standard equipped with a dot-matrix LCD display and magnetic buttons, with data storage and report output functions. An optional solar panel is available.
Different flow restriction devices can be selected for the ACU10FM battery-powered flow meter according to the needs (see the selection table - flow restriction device type). The corresponding technical parameters will also be slightly different, please refer to the integrated multi-variable orifice plate flow meter [P], integrated multi-variable V-cone mass flow meter [M], and integrated multi-variable V-cone mass flow meter [B]. Please consult the manufacturer if anything is unclear.
The ACU10FM battery-powered flow meter is used for the measurement of gas, liquid, and steam in the petroleum, chemical, power, pharmaceutical, food, papermaking, water treatment, metallurgy, cement, and glass industries.
