Product Description

Household Ultrasonic Water Meter
Overview
Ultrasonic water meter is intelligent measuring instruments by the temperature sensor, flow sensors and calculators. Calculator used the sensor and through the water of time difference to collect temperature differences and sound waves to complete accurate measurement of water flow. And can provide important application and data for many applications in the pipeline.Mainly used for water metering and monitoring water flow, such as domestic water, central air conditioning systems, equipment, etc.

Installation:
How to use: Touch the circular touch area on the right side of the water meter display and cycle through the data.
Installation positions of all parts of the flow meter should avoid being approached by sun light, flooding, freezing, chemicals and electromagnetic pollutions, and should facilitates dismounting and metering.Installation of ultrasonic water meter
1) Before installation should thoroughly clean the system piping,and clear the sand and other debris, avoid water meter failure;
2) Body level or vertical installation, Building water meter installation should be less than 0.8m from the ground;
3) Water flow direction should be consistent with the direction of the arrow marked on the meter body;
4) Before and after the pipe diameter to be consistent with the body diameter;
5) When installing the water meter, should be reserved length of
DN*10 in front of the water meter. Or should be reserved the length of DN*8 behind the water meter. (DN is the diameter of the water meter).

Daily maintenance
1. Regularly patrol inspection should be conducted to check the operating status and to see if the voltage of the battery after the flow meter is installed.
2. Specialized person should be resorted to have the battery changed when the flow meter operates more than 8 years,the monitor shows unclear data or the voltage indicates less than "3.2V", in case affecting the normal performance.
3. Long press 5S at the temperature interface, if the 4th screen shows "d 0000014"means the empty pipe or not full pipe.
Transport & Storage
  1) Transport: Meters should avoid being approached by rain,frost, fog after the encasement ,and should be handled as per" This side up" and avoid being damaged by extrusion ,collision ,etc. Transport conditions as per the standard of JB/T9329.
 2) Storage:. The warehouse should be acid-free ,base -free ,inflammable-free toxic chemicals-free and other mordant gas and objects. Avoid being exposed to direct sun light and strong electromagnetic interference.
