Longreen Technology Development Limited

Profile
A certain amount of water as defined by meter body passing through makes piston move. The measuring structure records its movements. Movements times defined amount making total amount of water passed registered.

Features
1. Rotary piston structure. It registers total amount of water passed in the tube by calculating how many times the piston rotates.
2. Dry and wet type are both separated from water so as to keep the registering clear.
3. Registering is stable and high-graded measurement. Easy to install.
4. Long endurance with no rotating inclination and long work life.
5. Various types available to register pure water or to be installed in any position.
6. Remote transmission device can be added upon request.
7. Different structures and specifications with beautiful appearances are available.
8. Meter bodies can be of copper, SS or plastic.
9. All technical figures are conformed with GB/T778.1~3-1996 which is equivalent to IS04064 Standard Class C.

Working condition
L Water temperature≤ 45º C
L Water pressure≤ 1Mpa (≤ 0.6Mpa for LXH-8S).

Maximum permissible error
L From the minimum flow-rate (qmin ) inclusive to the lower zone of the transitional flow-rate (qt ) exclusive: ± 5%.

The water enters the meter from the inlet of the meter body and impacts the vane wheel at the tip of the vane blades to make it rotate. The water flows out from the outlet of the body. The rotation of the vane wheel (proportional to the velocity of water flow) is transmitted directly to the central gear in the vacuum-sealed register by the magnetic coupling. The sealed register totalizes and indicates the water volume passing through the meter.

Working condition
-Water temperature≤ 50º C (Hot water meter≤ 90º C)
-Water pressure≤ 1MPa (PN: 1.6MPa/16bar)
-Δ P≤ 0.1MPa
Accuracy
-From minimum flow-rate (qmin) inclusive, to transitional flow-rate (qt), exclusive: ± 5%
-From transitional flow-rate (qt) inclusive, to overload flow-rate (QS), exclusive: ± 2% (Hot water meter: ± 3%.

Features
1. Wet, dry, liquid sealed
2. For hot or cold water
3. Small, light
4. Brass body or plastic body, optional
5. Brass body can be painted or nickel coated
6. High accuracy
7. The meters conform to ISO4064 Standard Class B or Class C.

Use ultrasonic flow measurement technology, no mechanical moving parts drift diameter design, no pressure loss, cut down the electric consumption of the pump and help untilities reduce cost.

Features:
Low in initial flowrate, and the min. Flow velocity measured is0.002 m/s;
Measurement cycle 1 time per second, battery powered (One battery can work
continuously for 6 years);
Multi-channel construction design, double cross section measurement, and be able
to ensure the measurement accuracy to the largest extent;
Be able to work at any flow point for long time;
IP68 of the whole meter, for each unit of the meter is IP68 designed;
Micro-consumption design, less than 0.0008W;
Drift diameter design, no pressure loss.
Operating on velocity-difference principle, the LG-UWM68 series is specially designed for urban water supply and building-use. The conventional water meters suffer from the drawbacks that they are only operable at a higher flowrate and are insensitive to a small flowrate. However, the LG-UWM68 series water meter can help tackle the bottleneck. And the meter is highly adaptable to diversified industrial conditions
Due to the use of ultrasonic flow measurement technology, it has no mechanical moving parts drift diameter design, no pressure loss, cut down the electric consumption of the pump and help the enterprises reduce cost
Be able to work at any flow point for a long time and high in reliability, immune to magnetic interference
Battery-powered capable of operating continuously for a period of over 6 years with a single cell
High sensitive to minimal flowrate and high in measuring accuracy
Capable of performing various output function, and it is capable of making wireless transmission of meter reading to form a monitoring system via the GSM network to monitoring the meter's running status and the pipe network conditions.
Three design versions are available, i. e. The ordinary version, 2-way version and fire water version are cater to different needs of users
Ordinary version: Measurements of the flowrate and cumulative running time in positive direction
2-way version: Capable of measuring flowrate, cumulative flowrate cumulative running time in positive/reverse direction;
Fire water version: Much bigger range ratio, and specially designed for fire water.
CE: 2004/108/EC
The meter is in conformity with Standard on Measurement of Water Flow in Fully Charged Closed Conduits_Meters for Cold Potable Water and Hot Water GB/T 778-2007-a standard is issued by the People's Republic of China
L Ex-factory calibration of the meter is made in conformity with Standard on Water Meter for Potable Cold Meter JJG162-2009- a standard is issued by the People's Republic of China.
