LXSG-15”«25Y Rotor type
dry water meter with photoelectric transmission of signal
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 the electrical signals to the secondary measurable
appliances.
Characteristics: The product
of this series is rotor type dry water meter with magnet-driven
type wheels and needles between the impeller and counter for combined
display.
It is convenient to get clear readings from the meter with the anti-freezing
function.
The signal is transmitted by the photoelectric sensor that will
transform the volume of water to electrical signals for transmission.
The location of signal transmission can be different. You can select
to send one signal for each 10 liter flux.
Application condition:
Water temperature is equal to or less than 40C
Water pressure is equal to or less than 1Mpa
Signal type:
signal is transmitted by photoelectric single pulse or photoelectric
double pulse.
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 ”Ą5%
The maximum error allowed for the high zone from the separating
flux(qt) to the over loading flux (qs)
is ”Ą2%
Installation requirement:
1ӢThe water meter must be installed in horizontal level with reading
side upward and arrow direction must be the same as water current
direction.
2ӢWater 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.
