Using photoelectric direct reading technology, the window value of the water meter is directly read, and there is no pulse accumulation error;
there is no power supply in the meter, and the direct reading device is powered on only at the moment of meter reading;
the direct reading water meter does not need to be initialized, and the maintenance workload of the meter reading system is small;
The meter address can be flexibly set with
M-BUS bus standard. Ordinary two-core cables are connected without distinguishing between positive and negative polarities, and at the same time, data communication and meter power supply functions can be completed.
tree structure wiring is convenient for construction and maintenance.
direct reading and remote transmission dry water meter
The direct reading and remote transmission dry water meter is made by adding photoelectric sensor and intelligent communication module on the basis of the traditional mechanical multi-flow rotor dry water meter. The meter adopts the patented integrated photoelectric direct reading technology, and the sensor is isolated from the counting gear without mechanical contact. The counter part is treated by vacuum, which is isolated from the outside air and the water to be measured, so that the counter is always clear and has no atomization; The meter head part is sealed and waterproof, with anti-magnetic function.
products include: direct reading remote cold water meter and direct reading remote heat transfer water meter.
Basic table parameters:
The measurement accuracy grade meets the ISO464 B standard.
water temperature: cold water meter: ℃ ~ 4℃; Hot water meter: ℃ ~ 9℃.
water pressure: ≤1MP.
direct reading remote liquid-sealed wet cold water meter
the counter of direct reading remote liquid-sealed wet cold water meter uses the patented technology of integrated electronics-intelligent remote direct reading module to realize digital remote transmission of data, and the casing is made of high-quality corrosion-resistant cast iron or high-quality brass. The sealed character wheel will not touch the water flowing through the water meter, so that the reading will always be clear and easy to read. The meter is fully sealed and waterproof, and can be used normally in the immersion environment.
Basic table parameters:
The measurement accuracy grade meets the ISO464 B standard.
direct reading remote direct drinking water meter

Direct reading remote transmission large-caliber water meter (RS485)
Advanced and mature patented direct reading meter reading technology of Integrative Electronics is adopted to directly read the window value of the base representation number and output the cumulative flow data signal of the water meter, without any disadvantages such as secondary metering error of the pulse signaling water meter. The meter reading circuit only works at the moment of meter reading, and its reliability, anti-interference and service life are far higher than other similar products. Based on dry detachable water meter, the products include cold water meter and hot water meter.
as a standard intelligent instrument, it can communicate with RTU, PLC and meter reading device of the third party by RS485 interface and standard communication protocol.
it can be used with various intelligent terminals and applied to urban water supply enterprises, water resources management departments and other automation systems that need water flow measurement and management.
