    Digital remote water meter

    Product introduction:


    The photoelectric direct-reading water meter is a relatively high-priced remote-transmission water meter composed of an electronic remote transmission module and a mechanical metering part. There are two types of meter reading methods for the photoelectric direct-reading water meter: First, the on-site mechanical part directly reads and captures water data. . The second is to query the water data on the computer through remote data transmission and charge directly. The photoelectric direct-reading water meter manages key memory functions and can also store water consumption data for each user. Digital remote water meter can be measured through mechanical display and remote data, which doubles to ensure more accurate water data.

    Features:


    1. The photoelectric direct-reading water meter directly reads the counter dial number of the meter, that is, the "window value". There is no need to set parameters such as the bottom number and the table constant in the table. There is no need to store data and there is no cumulative error. The history of accumulated pulses and converted values has ended. The electronic part of the direct reading meter is completely separated from the counter and other devices in the meter without mechanical contact, which does not affect the measurement accuracy.

    2. Photoelectric direct reading water meters directly transmit data, not pulse signals. Not only is it not affected by mechanical vibrations, it also has high anti-interference to electromagnetic interference, so it can achieve stable, accurate and reliable measurement in complex use environments;

    3. Photoelectric direct-reading water meters do not require power supply for daily work. This is a revolutionary technological progress, avoiding measurement errors and a large amount of maintenance work caused by unstable or faulty power supply;

    4. Since the photoelectric direct-reading water meter collects the position of the counter wheel of the mechanical counter (not the pulse), when the meter is reversed, the meter reading data is still consistent with the reading of the meter;

    Installation requirements:


    1. The water meter must be installed horizontally so that the reading of the water meter faces upward and the direction of the water flow is the same.

    2. Flush the pipes before installing the water meter.

    3. The water meter must be installed in a dry environment for easy disassembly and maintenance. It is recommended to install it in a special water meter box.

    4. Valves must be installed before and after the water meter.
