Benefits
- Reliability
- Accuracy
- Own software
- Ensuring the operation of the water meter in three modes: Warehouse, Verification, Network Operation
Scope
Individual cold and hot water meters.
Principle of Operation
Counter modules of individual water meters provide:
- reading of pulses (rpm of the impeller) of the spillage part of the water meter
- conversion of the number of pulses (impeller revolutions) to the unit volume of water that has passed through the overflow part of the meter
- display of information about the volume of water that has passed through the meter overflow section
- transmitting information over the radio channel to a remote device (base station) via LoRa (868 MHz)
- operation in three modes: Warehouse, verification, Network Operation using own software FLORA
- recording the impact of an external magnetic field on the counter
Counter Module Configuration
- Specialized software FLORA
- Registration and control module with a display that provides information output (consisting of at least 5 characters)
- Controls for switching operation modes of the counter module
- Remote data transfer module with support for LoRa technology
- Autonomous power source that ensures the operation of the counting module
