Jing Chuan JC250 metal tube

I. Product Overview:
Metal tube (also known as 'metal tube rotameter') is commonly used in industrial automation and process control using a variable area measuring principle of flow measurement instruments, it has a small, large detection range, easy to use features It can be used to measure liquid, gas and steam flow, especially suitable for small medium flow measurement of low velocity flow.
The series of smart meter for on-site instruction type, can be divided into 'the next entry on the left and lower right out into the side' three installation forms are widely used, petroleum, chemical, power generation, pharmaceutical, food, water etc. complicated, harsh environmental conditions, and flow measurement of various media conditions in the process.
Second, the principle:
Metal tube variable area flowmeter to float in the measuring tube varies with changes in flow, when the fluid flows through the pipe up, the float moves up, at a certain position of the float buoyancy and float suffered gravity reach the balance, flow annulus area at this time float orifice plate (or the cone) between constant. Annulus area and the height is proportional to the rise of the float, i.e., the size of the float rises in the measurement position represents the flow tube, the float changes position transmission in the form of magnetic coupling to an external indicator, the indicator follows the float moves a pointer, and with the cam plate so that the size of the pointer indicates the linear flow rate values.
Third, the product features:
1, the sturdy all-metal structure design type rotameter
