Product Usage
The horizontal detachable spiral wing dry cold (hot) water meter is used in industrial and mining enterprises to measure the total amount of cold (hot) water flowing through the tap water pipeline.
Usage conditions
Temperature rating: T30 (cold water) T90 (hot water)
Water pressure level: MAP 10 / MAP 16
Pressure loss level: △ P 10
Indication error limit:
From the low zone including the minimum flow rate (Q1) to excluding the boundary flow rate (Q2) ± 5%
From high zone cold water including boundary flow (Q2) to high zone cold water including overload flow (Q4) ± 2%, hot water ± 3%
main features
Dry type, magnetic transmission, with magnetic shielding and anti-interference function, vacuum sealed counter, anti condensation and atomization, can maintain clear readings for a long time;
Using high-quality materials with stable and reliable performance; Low pressure loss.
The series has strong universality, and there is no need to remove the water meter from the pipeline. Simply open the upper cover to remove the movement for repair or replacement;
The sensor is plug and play, sturdy and reliable, and easy to install and maintain. Pulse transmission, using sensors such as reed switches and magneto resistive elements, with strong anti-interference ability and long service life. The pulse constant is 10 imp/m ³ or 1 imp/m ³,
The length of the lead wire is 1.5m or 5m, and special lengths can be provided as required.
