The single-jet water meter "Pulsar" with a pulse output is designed to measure the volume of hot and cold drinking water according to SanPiN 2.1.4.1074-01 and network water flowing through the pipeline in cold and hot water supply systems. The device is equipped with a pulse output that sends pulses to a secondary device that counts the pulses and transmits information to the control room. This allows you to read data without direct access to the device and even without visiting the apartment in which it is located.
