Can be installed in any position, vertically or horizontally, dial facing upwards, downwards or side-way, water flowing downwards or upwards. With internal non-return valve. Not for use of pit application. For outdoor use, please refer to DAE MJ-100c, DAE PD-100 or DAE U-100. This is a Piston Positive Displacement water meter which may have clicking noise (Fixing the meter to a supporting bracket can minimize it). Cloud Metering available (2nd picture) with DAE CC2030 Gateway. CC2030 will collect water usage from DAE AMR (for 16 meters) or AMR130 (for 1 meter) and send them to cloud server through Ethernet. With PC, cell phone, the landlords can see real time data, monthly water usage & billing reports to their tenants. If there is abnormal usage (ex. Broken piping), an email alert will be sent to your cell phone. No IT guy required. Just connect wires as per a simple picture (see video) & ready to go. Ready for use with DAE CO-10 (Electronic Pulse Counter) or DAE CO-10 KIT - An inexpensive remote reading solution (6th picture). Can also use with DAE AMR130 (Auto Meter Reading Module for single water meter) and AMR (for 16 water meters) for remote reading (5th picture). CO-10 or AMR130 will be purchased separately.
