Overview
Enviro Testers’s Electromagnetic Water Air Gas Flow Meters for Industrial Measurement is specifically designed for the water industry, meeting the requirements of urban water supply and water resource management systems (RTUs). It provides information management services to ensure accurate water bill calculations. Widely used in field stations without power supply, such as urban water supply, sewage treatment, and water conservancy projects, it serves the water resource management sector.
Features
- Low-power design with a 3.6V lithium battery pack, featuring an excitation current of ≤50mA, ensuring uninterrupted operation for approximately 5 years and easy battery replacement.
- The display features an LCD large-screen backlight display with full Chinese menus, supporting automatic bidirectional measurement. It shows real-time flow rate, velocity, pressure, cumulative total flow (10-digit display), battery level, clock, and alarm indicators.
- The measuring tube contains no movable or obstructive components, preventing entanglement or blockage, with zero pressure loss for long-term reliable operation;
- Wide measurement range: Flow velocity measurement ranges from 0 to 15 m/s.
- Measurement stability: The accuracy remains unaffected by variations in physical parameters such as temperature, pressure, viscosity, and density of the measured medium.
- Features pulse output, RS485 interface, and GPRS wireless data transmission (compatible with GSM, WCDMA, and CDMA networks);
- Easy to debug with non-contact operation, no need to open the meter cover;
- Features 8-stage linear correction;
- Store 1000 records with built-in black box functionality.
