Hade HTZ Series Gas Turbine Flow Meter | DN50 to DN400 | 4-20mA
· High Measurement Accuracy
Accuracy class up to ±1.0% (or ±0.5% for high-precision models), with excellent linearity and repeatability for precise gas volume measurement.
· Low Pressure Loss
Optimized impeller design results in very low pressure drop, reducing energy consumption and minimizing impact on pipeline pressure.
· Intelligent Digital Display & Multiple Outputs
Equipped with LCD display showing instantaneous and total flow; supports 4-20mA, pulse, RS485, and GPRS/IoT remote transmission.
· Explosion-Proof Safety
Available with Ex d II BT4 Gb or Ex ia II CT4 explosion-proof certifications, safe for use in hazardous Zone 1 and Zone 2 gas environments.
· Wide Flow Range
Turndown ratio up to 1:10 ~ 1:20, capable of accurately measuring both small and large flow rates in a single meter.
