LYHY-8 Cubage long-range
transmission Water meter for purified water
Function:
¡¤The function of this product is to measure the total flux of drinking
water passing through the water pipe and transform the volume of
water usage to electrical signals for transmission. 
Characteristic£ºThe total flux of drinking water through the pipe
is recorded by the principle of piston rotation for this kind of
meter.
¡¤ Counter is seal-packed in vacuum bag to maintain the clear reading
in long term.
¡¤ Quality material is chosen with reliable performance .The flux
is very small when initiating this meter and measurement is very
accurate. The outer cover of this meter is made with stainless steel
materials that are nice in looking and reliable in application.
¡¤ Magnetic sensor is used which ensured the steady performance and
reliability.
Each time with 1 liter water passing through , there will be one
electrical signal sent out.
Application Condition:
Water temperature is equal to or less than 40¡æ, but must be more
than 0¡æ
Water pressure is equal to or less than 1Mpa.
Type of signal:
The signal is transmitted by dry reed pipes or hall
components£¨If transmission by hall components is required, please
make an additional statement when purchasing£©
The maximum error allowed:
1)The maximum error allowed for the low zone including the minimum
flux£¨qmin£©,with an exception of separating flux is ¡À5%.
2)The maximum error allowed for the high zone from the separating
flux to over loading flux is ¡À2%.
Installation
requirement:
The water meter must be installed in horizontal level with reading
side upward and arrow direction must be the same as water current
direction.
¡¤Water pipeline needed to be washed or cleaned before the installation
of water meter.
¡¤The water meter must be installed in a dry environment and be convenient
for assembly,disassembly and maintenance.
It is suggested that the water meter be installed in a box specially
designed for water meter. Valves must be installed both in the front
of meter and at the back of the meter.
