Product Series
An optional pressure regulator (constant flow controller) can be fitted to form a purge device used for auxiliary measurement of level, density, and pressure.
High accuracy, good repeatability, fast response, pulse signal output, 4～20mA standard analog signal output, simple structure, easy installation, use and maintenance. Filters, air eliminators and rectifiers can be supplied as a complete set.
HART communication protocol, MODBUS communication protocol (configured RS485 communication interface)
1. Simple structure, easy installation, accurate measurement, no need for actual flow calibration. 2. Low manufacturing cost, wide range of applications. 3. Corner pressure tapping, flange pressure tapping, radial pressure tapping. 4. Moderate accuracy, accuracy level 0.5~1.5. 5. Can measure the flow of gas, liquid, and steam, with a wide range of adaptability. 6. Nominal diameter: DN50~DN1000 (orders exceeding this range can be negotiated)
By adopting an equal pressure ring structure, the sources of measurement errors are reduced. The average static pressure of the pressure tapping cross-section upstream and downstream on the flow meter plate is introduced to the differential pressure transmitter, which weakens the influence of the velocity distribution distortion caused by the local resistance upstream on the accuracy, and the actual accuracy is closer to the basic accuracy.
Integrate a flow restriction device (standard orifice plate, nozzle, annular orifice plate, etc.) with a differential pressure transmitter.
High accuracy, outflow coefficient uncertainty ±0.7%～±1.5%
1. For rectangular duct airflow measurement 2. Easy installation, compact structure, and low maintenance 3. Low pressure loss, energy saving 4. Inlet equivalent diameter: D=1.13(WH)0.5≤1200mm 5. Accuracy level: 2.5 ~5.0
An insertion Venturi tube is a classic Venturi tube or double Venturi tube with a small diameter inserted into a circular pipeline. By measuring the flow rate of the inserted tube, the flow rate of the entire pipeline can be obtained. It can be used in the flow measurement of larger diameter gases (such as coal gas and flue gas).
Measuring high-viscosity media, suitable for liquid-solid mixtures containing suspended particles
Accuracy levels: 1.0, 1.5, 0.5 (requires actual flow calibration); Repeatability: 0.1%; Measurement range ratio up to 15:1.
1. Robust structure, stable performance, high temperature resistance, and long lifespan; 2. High measurement accuracy, 1/4 of that of ordinary nozzles; 3. Straight-through pipeline, not easily blocked; 4. Pressure tapping method: throat pressure tapping; 5. Nominal diameter: DN(100~600); 6. β value range: 0.25~0.5; 7. Shorter straight pipe section requirement: 20D0 before, 10D0 after (Note: D0 is the actual inner diameter of the process pipeline); 8. Measurable fluid Reynolds number (Red) range: ≥1×106.
