Sell DN200 Spiral Vortex Flow Meter DN200 Spiral Vortex Flow Meter Direct Sales

Description :

　　This product can work simultaneously with external power supply and battery power supply. Under normal circumstances, it is powered by 24V. In case of emergency or power outage, the built-in battery can continue to supply power, ensuring the normal recording and monitoring of data.

　　1、 Ordering Notice:

　　1. When ordering this product, users should pay attention to the nominal diameter of the pipeline, flow range, nominal pressure, medium pressure, and medium temperature range

　　Choose appropriate specifications for the surrounding and environmental conditions, and indicate the explosion-proof level requirements for use in hazardous areas.

　　2. Flow meters are generally of the basic type, with industrial and mining pulse output and RS485 communication interface. If other accessory output functions are required, please specify them when ordering.

　　2、 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.

　　3、 Structure:

　　1. Vortex generator

　　Made of aluminum alloy, spiral blades with a certain angle are fixed at the front of the shell contraction section, forcing the fluid to generate strong vortex flow.

　　2. Shell

　　It is equipped with flanges and fluid channels of a certain shape. Depending on the working pressure, the shell material can be cast aluminum alloy or stainless steel.

　　Intelligent flowmeter integrator

　　It consists of temperature and pressure detection analog channels, flow detection digital channels, as well as microprocessor units, LCD driver circuits, and other auxiliary circuits, and is equipped with output signal interfaces.

　　4. Temperature sensor

　　Using Pt100 platinum resistor as a temperature sensitive element, its resistance value corresponds to temperature within a certain temperature range.

　　5. Pressure sensor

　　The piezoresistive diffusion silicon bridge is used as the sensitive element, and its bridge arm resistance will undergo expected changes under external pressure. Therefore, under a certain excitation current, the potential difference between its two output terminals is proportional to the external pressure.

　　6. Piezoelectric crystal sensor

　　Installed at the throat near the expansion section of the shell, it can detect the frequency signal of vortex precession.

　　7. Racomer

　　Fixed at the outlet section of the shell, its function is to eliminate vortex flow and reduce the impact on downstream instrument performance.
