Selling DN32 Spiral Vortex Flow Meter DN32 Spiral Vortex Flow Meter Direct Sales

Description :

　　This product is widely used in industries such as kerosene, chemical industry, power sector, metallurgical manufacturing, industrial boilers, etc. It is a gas flow detection instrument for measuring the volume flow rate and total amount of low viscosity gases in natural gas and gas pressure regulating station pipelines, as well as gas thermal measurement.

　　1、 Main features:

　　1. No mechanical movable parts, corrosion-resistant, stable and reliable, long service life, long-term operation without special maintenance;

　　2. Implemented mechatronics integration, eliminating the need for manual monitoring in daily measurement processes;

　　3. The installation conditions for the process are not strict, and the straight pipe sections upstream and downstream of the instrument can be greatly shortened compared to orifice plates and vortex flowmeters;

　　4. The measurement accuracy of the system can meet the current trade measurement requirements (≤ 1.5%);

　　5. The flow measurement range is wide (qmax/qmin=15-20), which can effectively work in small flow areas that orifice plates and vortex flowmeters cannot access;

　　6. Small size, light weight, and convenient offline calibration;

　　7. The measurement signal can be displayed locally or transmitted remotely as needed.

　　2、 Structure:

　　1. The sensor includes a vortex generator, detection element, rectifier, and housing.

　　The vortex generator is composed of specific spiral blades, which are fixed at the front end of the shell contraction section, forcing the fluid to generate strong vortex flow.

　　The detection element is installed near the throat of the expansion tube, and the frequency signal of vortex precession can be measured using thermal, piezoelectric, strain, capacitive, or fiber optic detection elements.

　　The rectifier is fixed at the outlet of the flowmeter body, and its function is to eliminate vortex flow to reduce the impact of downstream flow state on instrument measurement.

　　The shell is designed as a flow channel with a certain shape to form vortices, fix and protect the components installed inside, and connect them to the pipeline through flanges.

　　2. Conversion display instrument

　　The weak voltage signal detected by the piezoelectric sensor is amplified, filtered, and shaped into a pulse signal whose frequency is proportional to the flow rate, and then counted and displayed by the display instrument. The display device is equipped with an output interface to output various signals. The measured gas medium can be compensated for temperature and pressure, converted to volumetric flow rate under standard conditions, and displayed.

　　3、 Installation:

　　1. It cannot be installed in places with strong vibration, and when the pipeline is long, the vibration generated by the pipeline must be eliminated upstream and downstream of the sensor.

　　2. When using an external power source, the flowmeter must have a reliable grounding and must not share the ground wire with the high-voltage system. During pipeline installation or maintenance, the ground wire shared by the welding system must not be overlapped with the flowmeter.

　　3. When installed outdoors, the upper part should be covered to prevent rainwater from entering or direct sunlight from affecting the service life of the vortex flowmeter.

　　4. In order to facilitate maintenance and not affect the normal transportation of fluids, a bypass pipeline must be installed. When the gas contains larger particles or longer fiber debris, a filter must be installed on the vortex flowmeter.

　　5. Flow meters should be installed in accordance with relevant explosion-proof regulations, and safety regulations should be followed during installation and maintenance.
