2BEVP-AGILWRPMIU301NBIoT Meter Interface Unit

NBIoT Meter Interface Unit M IU User Manual 1. Product Usage Non-magnetic remote transmission module (AGIL WRPMIU 301 ) integrates multiple functions into one, including data collection, precise measurement, two-way communication, data calculation and storage, etc. This module strictly follows 3GPP TS 36.101 and uses standardized NB-IoT base stations and integrated smart metering platforms for efficient and secure data interaction and centralized equipment control. 2. Working Principle AGIL WRPMIU 301 can gather metering signals from water meters using non-magnetic coils and other sensors, storing the accumulated readings in an MCU. This module has the capability to report these cumulative readings either by magnetic induction triggering or by actively sending them at pre-set time intervals. Subsequently, these data are displayed on a comprehensive meter reading platform through a specific application communication protocol. Conversely, the integrated meter reading platform can also transmit specific commands to the module on the water meter. 3. Packaging information and precautions 3.1 packing list Serial Number Name Quantity 1 Non-magnetic remote transmission module 1 piece 2 Battery compartment cover 1 3 Special tool for battery compartment cover 1 4 connecting nut 1 5 Sealing gasket 1 6 manual 1 serving 7 Infrared handheld machine 1 8 programmer 1 3.2 Storage and disposal after use This device should be stored in an environment of 0~55°C (avoid direct heating), otherwise it may affect the normal operation of the MCU inside the device; This device contains batteries, after the product is scrapped, it must be handed over to the relevant electronic product processing agency for recycling and unified processing to prevent environmental impact. M IU User Manual 4. Module Installation 4.1 Installation steps 1. Install AGIL WRPMIU 301 into the water meter buckle and align it with the fixing hole . 2. Tighten 1 stainless steel screw at the fixing hole . M IU User Manual 4.2 Installation site signal judgment The signal of the module installation position can be judged by the following two data: 1. CSQ: received signal strength; the larger the value, the better the signal. When the value is less than 10, it means that the MIU installation environment signal indicators are very poor, which will cause the MIU to frequently fail to upload data. (This data is used to judge on-site NB network performance) . 2. RSRP: Received signal energy; the larger the value, the better the signal. When the value is less than -105, it means the MIU installation environment signal index is very poor. (This data is used to judge on-site NB network performance) . two. Signal parameter range reference: 1. CSQ: signal strength, range 0-31, the larger the value, the better. 2. SNR: Signal-to-noise ratio, above 0, the bigger the better. 3. RSRP: Signal receiving power, -60 ~ -130dBm, -60 ~ -100dBm good. 4. ECL: Coverage level 0-2, 0 is excellent, 1 is average, and 2 is poor. M IU User Manual 5.
