Wet-type pulse remote transmission water meter (hereinafter referred to as WPR water meter) is Hanwei’s self-developed remote meter for the actual needs of daily water consumption, which is convenient for remote meter reading and control. It adopts wireless communication to realize remote reading of the water meter, effectively avoiding the door-to-door meter reading by the Water company/Bureau. This product also has a valve control function ( optional ), which is convenient for the water company/bureau to control the water consumption of the pulse -type remote water meter, making remote meter reading and control more convenient and reliable, while saving manpower, material and financial resources. Effectively increased productivity.
