LXSF-15¡«50Y Rotor type
liquid sealed water meter with signal transmission function
Function:
The function of this product is to measure the total flux of drinking
water passing through the water pipeline, and transform the volume
of water usage to electrical signals for transmission.
Characteristic:
The meter of this series is liquid sealed wet type with transmission
in the long-distance range. Wheels parts are sealed with special
liquids.
It is very convenient to get clear readings from the meter. The
meter is maintained with clear display and anti-freezing function.
¡€The signal is transmitted by hall components or dry reed pipe that
will transform the volume of water to electrical signals for transmission.
The location of signal transmission is different. You can select
to send one signal for each 10 liter or 100 liter water¡€
Application condition:
Water temperature is equal to or less than 40¡æ
Water pressure is equal to or less than 1Mpa
Signal type£ºSignal is transmitted by dry reed pipe, hall components
or photoelectric cell.
The maximum error allowed:
The maximum error allowed for the low zone including the minimum
flux(qmin),with an exception of separating flux(qt) is ¡À5%
The maximum error allowed for the high zone from the separating
flux(qt) to the over loading flux(qs) is ¡À2%
Installation requirement:
1¡¢ The water meter must be installed in horizontal level with reading
side upward and arrow direction must be the same as water current
direction.
2¡¢Water pipeline needed to be washed before installation of water
meter.£»
3. The water meter must be installed in a dry environment and be
convenient for 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.
