FTE-1780DSeriesGPRS remote transmissionIntelligent electromagnetic flow meter
Allows you to be anywhere with an internet connection
All can be achievedUltra distancePrecise flow measurement
Powerful Modebus RTU/RS-485 transmission methods, GPRS/3G/4G and other transmission methods, rich data carrying capacity, knowing the instantaneous and accumulated quantities of flow meters dozens of kilometers away in seconds,Pipe pressure value, battery power and other information. It's so easy to use and save trouble!
● FTE-1780D electromagnetic water meter is a direct-reading electromagnetic water meter that displays instantaneous flow and accumulated flow on-site. It is battery-powered and does not require external power. It adopts a high-definition LCD screen, making metering intuitive, convenient, and maintenance-free.
● The meter is easy to install - the meter can be buried underground or installed in a well.
● The IP 68 (NEMA 6P) design is independent of the installation position of the instrument in the pipeline and does not require a filter.
● Low pressure losses - The straight measuring tube ensures low pressure losses, even at high flow rates. Prevent excessive pressure at the pump station, causing pipe rupture and leakage.
● Zero Maintenance - Designed with no moving parts and a battery life of up to 6 years.
● Bidirectional Measurement - Bidirectional flow measurement using only one meter.
● Smart Meter - Leak detection, data logger functionality and error self-diagnosis using just one meter.
Applications:
● Secondary water supply pipe network,
● Large water users,
● Zone metering,
● Pipe network leakage monitoring
● Monitoring and measuring of water quantity

| Product name | Electromagnetic water meter | Ultrasonic water meter | Mechanical water meter | Description |
| Start flow | Low | Low | High | "High"; represents small flow that cannot be measured |
| Measuring Range | Wide | Wide | Narrow | "Narrow" means inaccurate measurement of small flow rates |
| Long term measurement accuracy | Stable | Transducer fatigue | Wear and tear | "Transducer fatigue" and "wear" mean that negative deviations are prone to occur during long-term operation. |
| Long term reliability | High | Relatively high | Lower | "Lower" means prone to failure |
| Effect of bubbles on measurement accuracy | Smaller | Larger | Smaller | "Large" means that it affects the measurement accuracy |
| Straight Pipe Run Requirement | Extremely low | Relatively high | Relatively high | "Higher" means that when the straight pipe section is not enough, the measurement accuracy will be affected. |
| Far transmission data | Accurate | Accurate | May be misread | "Misreading" means that the data read may not be consistent with the actual situation |
| Power Consumption | Relatively high | Lower | Basically no power supply required | "Lower" means the lithium battery has a relatively long life |
| Reliability | High | Relatively high | Lower | "Lower" means prone to failure |
| Price | High | Relatively high | Lower |
