Metal tube rotor flowmeter is a commonly used flow instrument in industrial, chemical and other automation fields, which can measure the flow of gases, liquids and other gases. Compared with glass rotor flowmeter, it has a longer service life and greater pressure resistance. Changzhou Chengfeng Instrument currently has a third-generation metal tube rotor flowmeter, which adopts an integrated inner and outer cone tube design, which is sturdy and simple. The measuring tube is *, the float can rotate, and it is not easy to block. The magnetic components are not affected by the geomagnetic field.
The metal tube rotor flowmeter consists of a measuring tube, a float, and an indicator. The float moves freely up and down in the measuring tube, changing the flow area in the pipeline. As the flow rate changes, the vertical position of the float in the measuring tube also changes accordingly. The position of the float is accurately transmitted to the dial of the indicator through a magnetic transmission system, indicating the change in flow rate value.
The metal tube rotor flow scoring system has both on-site indication and intelligent remote transmission types, with pointer display of instantaneous flow rate, LCD display of instantaneous and cumulative flow rate, standard 4-20mA current output, upper and lower limit alarms, HART protocol output and other functions, providing a wide selection space for different users.
Different configurations and functions will definitely result in different prices. There are various prices for metal tube rotor flow meters, mainly produced in different product types:
1. On site pointer type. That is, on-site indication type, which is the most basic function and cheap.
2. Remote transmission LCD type. The readings obtained from the instrument measurement are displayed on a LCD screen, which is more intuitive and comes with a 4-20mA output function. This type is much more expensive than the basic type.
3. Installation form. Metal tube rotor flow meters are often customized according to customer requirements for vertical installation, horizontal installation, flange connection, threaded connection, including side inlet and side outlet types.
4. Materials for production. Due to the factors of the measured medium, flow meters are made of different materials. Ordinary media do not require anti-corrosion and can be made of stainless steel 304. However, some corrosive media must use anti-corrosion materials such as stainless steel 316L or stainless steel 304 lined with PTFE, which naturally increases the price.
