Overview
These multipath ultrasonic gas meters (DN100-DN300) measure natural gas without wear, eliminating turbulence effects with path redundancy and converting to standard conditions via built-in pressure and temperature sensors. Titanium transducers, GPRS/NB-IoT remote management, self-diagnostics and battery backup suit custody transfer and process gas metering.
Key Features
- Utilizes ultrasonic technology to maintain long-term accuracy and no wear and tear;
- Multipath design detects multiple flow profiles, eliminating turbulence and asymmetric gas flow impact;
- Multipath offers redundancy capability and channel substitution technology for continued operation;
- Titanium alloy transducer employed possesses corrosion resistance, high-pressure resistance and anti-contamination;
- Wide Turn-Down ratio and excellent repeatability ensure stable measurement;
- Temperature and Pressure Sensors ensure accurate gas flow measurement;
- No pressure loss and ultra-low starting flow ensures monitoring of minimal gas consumption;
- Detachable transducer design for easy periodic cleaning;
- Integrated wireless module allows easy remote monitoring and meter status management;
- Automatic self-diagnostics, reducing equipment failures and downtime;
- Wired power supply with lithium battery for backup enhances system reliability;
