CUTE-LV SERIES ULTRASONIC WATER METERPRODUCT INTRODUCTIONCHANGZHOU CUTE INTELLIGENT CO.,LTD 1、 Overview CUTE serial ultrasonic water meter module is the core part to work with the base meter to measure and display the water flow. CUTE serires ultrasonic water meter with the M-BUS interface, The staff can read the meter data at any time by the remote reading management system with the M-BUS interface and other device. 2、Function and Characteristic2.1 Under voltage warning;2.2 Automatic error correction tech;2.3 Temperature sensor cut and short circuit warning;2.4 Flow sensor failure warning;2.5 High definition and wide temperature LCD;2.6 Wide range ratio;2.7 Lithium battery life is more than 6+1;2.8 Can read the meter data by infrared tool at the spot;2.9 With the M-BUS interface;3、Usage instruction1.The water meter operated by the menu, can change the work condition and display contents by the button on panel; There are 4 menu, the default is main menu, the change flow is as below:Main menu xxxxx.xxx m3【F】【I】【E】 Means the long press time 2s;1) Main menu: normal condition; 2) Error menu【E】 3) Information menu【I】 4) Verification program【F】 The screen is off when stand by, press the button to awake the meter and enter the main menu, which show the accumulated flow(above figure), long press to change menu and read the data you need, the screen will be off after 3 minutes without any operation except the verification program【F】.
