1. Product Overview
The solar-powered flow meter has been upgraded with an integrated equipment lithium battery (automatically charges in DC power supply mode can automatically switch to lithium battery for continuous operation for up to a month after power failure), with data storage and report output functions, and optional spare solar panels and wireless communication The solar-powered flow meter adopts multi-parameter measurement technology, replacing four instruments: differential pressure, pressure, flow, and totalizer, thus saving customers' purchasing and installation. The integrated flow meter uses full-parameter dynamic compensation technology to improve the accuracy and range of the instrument; full-range static pressure compensation technology to improve the accuracy of the or plate operation; and can be calibrated with the orifice plate integrated, with a calibration accuracy better than that of a separate instrument; specialization and integration in terms of functions; ifferent orifice plates can be selected according to needs (see the selection table - orifice plate type), and the corresponding technical parameters will also be slightly different. Please consult the for any unclear points.
2. Industry Applications
Solar-powered flow meters are used for the measurement of gases, liquids, and steam in industries such as petroleum chemical, power, pharmaceutical, food, paper-making, water treatment, metallurgy, cement, and glass.
