الوصف

It operates with ultrasonic flow measuring technology without any moving mechanical parts, and is high in reliability, less in maintenance work and no pressure loss is incurred.
 The meter is designed to operate with a micro-power consumption, and can be powered by either battery（a single battery can enable the meter to work continuously for a period of over 6 years ） It is sensitive to an initial flowrate as low as 0.**5 m/s and high in measuring accuracy.
 It is provided with various output functions. For instance, the GSM radio transmission function can be used to form a water fee control system for monitoring the working status of water meters. Single-path, *-path and *-path working patterns are available for selection.
