DN125 cast aluminum spiral vortex flowmeter

Description :

　　DN125 cast aluminum spiral vortex flowmeter

　　This product is equipped with two sets of signal detectors in the measurement area, successfully suppressing interference caused by pipeline vibration. It has been widely used in industries such as petroleum, petrochemical, power, metallurgy, and urban gas supply.

　　1、 Main features:

　　1. The built-in pressure, temperature, and flow sensors have multiple compensation methods for users to choose from, with high safety performance, compact structure, and beautiful appearance.

　　2. On site display of temperature, pressure, instantaneous flow rate, and cumulative total amount.

　　3. By adopting a new type of signal processing amplifier and unique filtering technology, the interference signals generated by pressure fluctuations and pipeline vibrations are effectively eliminated, greatly improving the anti-interference ability of the flowmeter and making small flow rates have excellent stability.

　　4. The anti-theft function is reliable, with password protection to prevent parameter changes.

　　5. Equipped with two-wire and three wire 4-20mA standard current signal output, pulse output, and RS485 interface.

　　3、 Installation:

　　1. When installing a vortex flowmeter, avoid places with high temperature radiation. If it is not necessary to install, some ventilation measures should be taken. In addition, do not install it in damp or water prone areas.

　　2. When installing a vortex flowmeter, it should be installed indoors as much as possible. If it is to be installed outdoors, it should also avoid places that are exposed to sunlight and rain. Do not install it in places with temperatures above 60 degrees Celsius and humidity above 95%.

　　3. The installation of the vortex flowmeter should avoid places with strong electromagnetic fields, otherwise it will be affected by magnetic field interference. In addition, ventilation measures must be taken when installing in environments containing corrosive gases.

　　4. In order to better repair the vortex flowmeter in case of malfunction, it is necessary to install it in a place that is easy to move.
