APPLICATION

The Moses Alternate is designed for accurate measurement of water consumption in households, apartment buildings and small commercial premises, where low flow sensitivity is important. The added valve and wireless controller give flow control capabilities to the system.

Static flow measurement - no moving parts, no wear and tear
Very high metering accuracy
Eliminates measuring deviations caused by sand, suspended particles or air pockets
Long-term measurement stability and reliability
9 digits, multi-line LCD. Total volume and instantaneous flow rate indication at the same time
Valve close/open automations based on a schedule or other sensor triggers; including leak, temperature, and flow thresholds

TECHNICAL FEATURES

Sensitive in low flows – starting flow as low as 0.01 gpm
Maintenance free device, battery lifetime > 16 years
Installation in any position
No straight pipe run needed
No measurement of air
IP68 protection class
Bi-directional flow measurement
Durable composite body
Measurement units: Gal-GPM, cubic feet - cubic feet/h
Strainer and check valve (optional)
Integrated LoRaWAN communication, US902-928 MHz band
- Radio will wake up and transmit data after 3 gallons of water has flowed through the unit
- It may take up to 8 hrs to see the first collection of data in portal.kairoswater.io
