It can be used for both hot and cold purposes (both heating and cooling can be measured), and the inlet and return water temperatures are optional, making construction and installation easy. No mechanical moving parts, no wear and tear, long service life. Measurements are not affected by poor water quality and maintenance costs are low. Using micro-power consumption technology, one battery can work continuously for more than 6 years. Using ultrasonic flow measurement technology, it can be installed at multiple angles, the instrument measurement will not be affected in any way, and the pressure loss is low. Using high-quality transducers and advanced measurement technology, the measurement accuracy is high and the stability is good. Both hot and cold uses (both heating and cooling can be measured). Supports NB-IoT, optical interface, RS-485, and M-Bus output interfaces, which can realize remote meter reading and facilitate centralized control and management by users.
Accuracy level 2 or 3, Temperature range 4~95℃, Temperature difference range 3~60℃. Water pressure level: MAP16.
●Use imported high-quality transducers ensure high accuracy and stability in flow measurement.
●No mechanical movement,no abrasive wear,suitable for poor water quality, low maintenance costs,up to 6 years battery life.
