HTZ Series Electronic Display Gas Turbine Flowmeter – Real-Time Data & High Accuracy

· 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.
