cold water meter

Liquid sealed water meter

the liquid-sealed water meter is a water meter which is used for preparing a liquid-sealed water meter by using a certain concentration of glycerin or the like in the meter digital wheel or the whole counter for meter reading. The definition of the seal isolated counter is not affected by external water quality, and the other structural performance is the same as the wet water meter. Liquid sealed cold water meter

Product description:

The hermetically sealed water meter is separated by rubber seal strip, and the sealing performance is good at room temperature. The technical gear of liquid seal meter is completely liquid sealed by special liquid, so it will not be affected by water quality, and the reading can be kept clear for a long time. It has no water under the lense of counter, can withstand pressure of water, cold and freezing weather, its figures show that part of the reading can be kept clear for a long time. But the manufacturing process of dry water meter is expensive. Due to the disturbance of external strong magnetic field, rust in water and natural demagnetization, the measurement data will be slower and slower in some case

Performance Characteristics

This water meter is a liquid sealed ,one of wet type water meter. the special liquid encapsulation of counter data wheel for reading windows to keep clear for a long time

water contact parts are made of high-quality anti-corrosion and anti-pollution materials

the connections of DN15-40 used standard screw thread

The connections DN50 are used flanged connection(cast iron body)

It has the advantages of low initial flow rate of wet water meter and clear reading number of dry small meter, which is especially suitable for poor water quality pipe network,.

it has the advantages of low initial flow rate of wet water meter and clear reading number of dry small meter. With high quality materials, the performance is stable and reliable; the measuring precision reaches the ISO 4064 Class C standard

you can choose different R3/Q1 ratio according to your demand

direct reding water meter

Passive direct reading water meter

Based on the traditional mechanical single-jet rotary vane wheel dry dial water meter, the direct-reading water meter with long-distance transmission (remote reading available)is made of photoelectric sensor and intelligent communication module, which is designed on the basis of the traditional mechanical single-jet rotary vane dry-type water meter. This phenotype adopts the patented technology of integrated photoelectric direct reading, the sensor is isolated from the counting gear, and there is no mechanical contact. The counter is vacuum-treated, isolated from the air and water measured, so that the counter is always clear and free of atomization. The meter adopts sealed waterproof treatment and has anti-magnetic function.
woltman water meter

Detachable Helix Woltman water meter

The LXLC detachable horizontal woltman type water meter is used to measure the total amount of tap water flowing through the pipeline. It cannot measure hot water, sewage and corrosive liquids. LXLC-80C~200C detachable horizontal woltman water meter, also known as “agricultural water meter”, is suitable for the measurement of water (such as groundwater) containing muddy, sand in the pipeline.
