WQLB Sonic Nozzle Gas Flow Standard Facility
Category： Sonic Nozzle Gas Flow Standard Facility
Product Description
Product Introduction
The device uses a sonic nozzle as a standard for accurate, automatic and efficient verification of speed flowmeters, volumetric flowmeters, mass flowmeters, and ultrasonic flowmeters. It is suitable for use in units such as measurement and testing institutions, gas companies and gas flowmeter manufacturers.
The device consists of a sonic nozzle, a stagnation container, a back pressure container, a buffer container, a flow meter quick switching mechanism, and a bus measurement and control system.
Product Features
1. Sonic nozzle multi-filter, clean without clogging.
2. The sonic nozzle accurately locates and measures leakage.
3. Temperature and pressure measurement accuracy is high, the bus real-time high-speed transmission of measured values.
4. The small-caliber flowmeter rotates and switches clamping rapidly, no need to replace the measuring section, saving space.
5. Pneumatic clamping table, easy and efficient.
6. The computer intelligent control selects the best nozzle combination to verify the different flow points.
7. Intelligent automatic verification.
