Product Details
Passive automatic control water meter
LXSJS-15E～20E
No electronic parts, all mechanical quantitative device, the realization of prepayment management.
Suitable for outdoor installation in rural areas with complex environment, without rust and corrosion.
Description
This water meter is the company's independent research and development, independent manufacturing of a new mechanical pre-purchase quantitative water meter.Can achieve full mechanical automatic control switch valve, manual setting pre-purchase tonnage of a water meter.This meter is accurate, easy to operate, easy to install, suitable for urban and rural water supply measurement and management.
Features
1.Safe and reliable: all mechanical structure, stable, anti - interference, and electricity independent.
2.Warning hint: when the remaining water is insufficient, the water output decreases slowly.
3.Real-time display: users can view the remaining amount of water through the reading window.
4.Automatic closing: when the water meter consumption reaches the amount of water purchased by the user, the valve will be automatically closed.

Installation and maintenance
1.Water meter selection should be based on the pipe often used flow rate is less than or close to the common flow rate of the water meter is appropriate, can not be determined simply by the pipe diameter water meter.
2.Water meter must be installed horizontally, counting up, the arrow direction of the case should be consistent with the flow direction, the top of the water meter should be left more than 200mm of space, in order to facilitate the purchase of water operation;Water meter must be installed in front of the valve, so as to disassemble and pre-purchase water meter.
3.Installation location should avoid exposure, freezing, pollution and water flooding, so as to disassemble and read the meter.
4.Before the new installation of pipes, be sure to wash the stones, silt, hemp and other debris in the pipe clean before installing the water meter, so as not to cause water meter failure.
5.To measure correctly, the tap should be higher than the meter.
6.Water meter should not be directly connected to the pipe, water meter and pipe should be connected by connecting pipe, sealing washer, connecting nut, disassembly, do not force hard wrench, so as not to twist the case water meter affect normal operation.
7.It is strictly prohibited to install and disassemble the water meter by yourself and install it improperly, so as not to cause damage to the metering machine and make the water meter unable to work normally.
