HOW TO USE
NB-IoT clap-on water
meter is used for measuring water flow rate through pipe via wireless NB-IoT network
uploading water consumption. Base meter and electronic module can be completely
separated for future maintenance and upgrade on site.
The water
meter adopts the advanced Non-Magnetic sampling technique. It is a kind of
technique that ensure high measuring accuracy, wide measuring range, and it not
affect by the water quality.
Water meter
will be timed uploaded data at 0 o’clock by default. These data including
frozen accumulated water consumption of the previous day, real-time accumulated
water consumption, signal value, battery voltage and so on. And If it is fails,
water meter will automatically replenish the data in the next cycle.
FUNCTIONS
1. Clap-on structure: The base meter and electronic module can be completely separated for future maintenance and upgrade.
2.Non-magnetic
sampling: Free
from
magnetic attack with the advantage of high measurement precision and stable
performance.
3. Alarm function: Water
meter
will automatically alarm when battery voltage is low.
4. Timed upload function: The data will be uploaded at 0 o’clock by default.
5. Storage function: Water meter can store frozen data for 12 months continuously.

INSTALLATION
1. Water meter installation should be complied with GB/T778.2 installation requirements.
2. It is suggested to install the filter in front of the ultrasonic water meter and install the valve in front of the filters to facilitate the maintenance and cleaning of the filters.
3. Wash the pipe before installation to avoid threads, tones or other sundries in the pipeline from causing malfunction of the meter.
4. Water meter should be installed horizontally (display face up).
5. Please leave enough space for repairing, and install according to water flow direction on the pipe.
6. Please do not apply too much force when connecting the ultrasonic water meter and pipe, to avoid damaging the meter body and causing water leakage.
7. Please do not knock the meter shell violently or cause strong vibration during installation, in case of damaging the equipment.

MAIN TECHNIQUES
1. NB-IoT technique: Signal network depth coverage (underground installation and piping well all can work normally)
2. Micro-computer and micro-storage technique：Highly integrated and highly reliable
3. Low power consumption PSM: sleep mode for power saving, messages are cached to prevent loss; eDRX: intermittent wake up mechanism supports message cache, shortening the message delivery cycle.
4. Totally sealing design: All of the circuits are sealed by polyurethane, there is no exposed electrode, and can be used in humid environment.
5. Massive connections and unified multi-service platform: Support multi-service co-deployment and scalability and multi-service data isolation and security decoupling. Support tens of millions of connections and even hundreds of millions of connections in the future.
