Description
Fixed volume provers are available in two types: bidirectional and unidirectional. Bidirectional volume provers have a small footprint, can be fixedly installed, and are easy to skid-mount. They have a 20:1 turndown ratio and are suitable for multiple sites and single-unit volume prover applications; unidirectional volume provers have low pressure loss and a large turndown ratio of 40:1, suitable for laboratories, metering stations, and applications with many flowmeter types.
Nominal Diameter: DN150~DN600
Flow Range: (2~3000)m3/h
Repeatability: Better than 0.02%
Reproducibility: Better than 0.05%
Features:
1. Can verify or calibrate the metering performance of volumetric and velocity flow meters with output pulse signals, widely used in the petroleum and petrochemical industries.
2. Allows in-situ verification or calibration of flow meters under operating conditions, overcoming errors caused by differences between operating and verification conditions. At the same time, it avoids errors caused by liquid evaporation.
3. Allows real-time dynamic leak detection of the volume prover conversion valve.
4. During verification or calibration, it is not necessary to start or stop the flow meter, eliminating errors caused by starting and stopping the flow meter.
5. The control system has a high degree of automation, with temperature and pressure compensation calculation, ensuring a stable and reliable verification process.
6. Advanced and sensitive detection switch technology; explosion-proof grade: Ex db llB T4 Gb.
7. Reasonable structure, with two structural forms: flat and folded.
