Battery-Powered Electromagnetic Flowmeter
Autonomous flow measurement for off-grid water supply systems—this flowmeter operates on 3.6V battery power for areas unreachable by outdoor power grids. Unlike AC-powered meters requiring costly cable trenching and electrical installations, battery operation with integrated GPRS wireless transmission enables deployment at remote tap water networks, isolated pump stations, agricultural water points, and distributed metering locations where grid power is unavailable or prohibitively expensive—delivering ±0.5% to ±1.5% accuracy with zero installation electrical work and real-time cloud data access from any location worldwide.

Flow Measurement Where Power Infrastructure Doesn't Exist
Six reasons battery power and wireless communication solve remote metering challenges
- Eliminate electrical installation costs—deploy where AC power is unavailable
- Real-time remote monitoring via GPRS—eliminate manual meter reading site visits
- Dual power capability—continuous operation through power outages
- IP68 submersible—operates reliably through flooding and submersion
- 0.6-4.0 MPa pressure range—one meter design serves multiple system zones
- Integrated or split configuration—optimize for installation constraints

Rapid Installation Without Electrical Infrastructure
Mechanical installation identical to standard flowmeters—add wireless activation for complete deployment
Critical Installation Requirements
1. GPRS Signal Strength Verification
- Mandatory pre-installation test—do not install in areas with <-110 dBm signal
- Use signal strength app or converter display to verify
- Test at installation height and location (signal varies with elevation)
- Consider external antenna for underground vault installations
2. Straight Pipe Requirements
- Minimum: 5D upstream, 3D downstream (D = pipe diameter)
- Recommended: 10D upstream, 5D downstream for custody transfer accuracy
- After pumps, bends, or valves: increase to 15D upstream when possible
3. Battery Life Optimization
Configure for maximum battery life:
- Sampling interval: 1 hour (vs. 1 minute for continuous monitoring)
- Transmission interval: 24 hours (batch transmit daily vs. real-time)
- Display: Disable LCD if not required for local reading
- Expected life: 4-5 years with hourly sampling and daily transmission
