lora water meter (1)

AMI SYSTEM INTRODUCTION SIMPLE IS SMART…..

System structure diagram as follows
· Server send commands to the data concentrator through network;
· Concentrator transforms the received commands into radio signal and send the signal to the water meters;
· Water meters respond and execute the commands accordingly;
· Water meters deliver the result or data back to the management center as per the original route after the actions finished.

Service
· Quality Gurantee: Water meter for 1 year;
· Support install guide & test in site;
· Date sheet can be sent to other management system easily.

Brief introduction

Technical characteristics:

1. The LoRa water meter adopts the integrated design of the meter valve and the built-in valve, which can realize the remote control of the data and the remote control valve. The pre-payment or post-payment methods can be selected. The prepayment method, automatic valve closing of arrears, is the preferred measuring instrument for water resources management and toll collection departments.

2.Each specification has a remote transmission type and card prepaid options to choose from. Remote transmission type, each water meter can serve as a route. The battery voltage can be checked in real time through the management software to facilitate replacement. The lithium battery can ensure the normal measurement of the water meter for more than six years.

3. High-precision, wide-range, high-definition LCD display of usage data, electromechanical dual display

The installation method is diverse, with horizontal installation or vertical installation for choice.

4. Low cost,the size of the water meter is the same, as long as it is equipped with different specifications of pipe joints and connection threads, different pipe diameters can be connected.

5. The moisture resistance of LoRa water meter is superior. It has passed the IP68 waterproof rating test and can be used with confidence.

Performance characteristics of wireless remote water meter LoRa

1. Low cost: use free SIM wireless measurement frequency band.

2. Reliability of data link: The coding adopts highly efficient cyclic interleaving error detection coding.

3. Low power consumption design: passive transceiver, high-capacity lithium-ion battery power supply, battery life of more than 6 years.

4. Diversity of meter reading modes: You can use the network meter reading method of the concentrator network, or you can use the wireless hand meter reading machine to read the meter while walking.

5. Long-distance transmission: In a complex urban environment, it also has a coverage of 1.2km. For long-distance nodes, it is connected by a multi-layer routing network.

6. Strong anti interference: Adopting the unique spectrum widening processing technology of LoRa, the terminals of different spreading sequences will not interfere with each other even if the same frequency is sent at the same time.
