Q
How to manage water consumption effectively to enhance efficiency of manual meter reading ?
A
Many clients have suffered from the inconvenience of meter reding for the environmental restricts of installartion site. EMS provides comprehensive Automatic Meter Reading(AMR) solutions to slove this problem. With integration of digital flow meters and communication interfaces, users can easily manage the water consumption through the telephone network, Internet, or mobile data network. Furthermore, AMR system of EMS can connect to not only our own water meters but also other ultrosonic water meters and electromagnetic waters meter in market with output signal in 4-20mA or pulse .
Q
What are the key factors users should consider when choosing and installing the flow meter？
A
Including the type of measured fluid, the size of type, the flow rate, the installation position, the installaton environment, and the expandability for AMR systems in the future.
Q
What factors should users consider when selecting the suitable water meter?
A
Priority should be given to the professional abilities of suppliers. An ideal supplier should be allowed to supply products approved by national and international certifications. The products reports of testing and calibration should also be available to ensure the measurment quality and accuracy of flow meters.
Q
How to judge if the water meter is operating normally, or not?
A
Under normal use, installed flow meters should have ability for conducing correct measurement. To judge if the flow measurement is under normal operation, users of EMS smart water meters can take adnantage of smart functions in LCD register, including "Leak Days", "Overload Days", "Static Days", "Magnetic Interferance Days", etc. By the assistance of diigtal technology, users are allowed to manage the perforamnce condiction of water meters efficiently.
Q
What is synchronous transmission?
A
Synchronous transmission means that the detected value of flow meter will be always same as that of communication interfaces. Even when the signal interruption happens, there will be not any difference between values of water meters and interfaces once the signal is recovered.
Q
Do smart water meters need external power supply? Will built-in battery suffers from the problem of the power shortage?
A
EMS smart flow meters have below advantages:
1. Connect to various monitoring equipments with digital communication, much more accurate than 4-20 mA.
2. With built-in batteries, the safety level of explosion-proof is much higher.
3. With built-in batteries, smart flow meters can still oprate even when power failure happens.
