High pressure rotameter is suitable for flow measurement of high pressure liquid and gas.
Standard type rotameter: DN15-DN50, can withstand 4.0MPa. High pressure rotameter: DN15-DN50, can withstand 25MPa. The pressure level of the jacket is 1.6MPa, and the special type should be negotiated with our engineers before selecting and ordering.
High temperature metal tube rotameter can be applied to temperature range: 100℃~450℃
The high-pressure rotameter adopts an advanced magnetic sensor that detects the change of the magnetic field angle without contact. And with a microprocessor system. It can realize liquid crystal indication, accumulation, and remote transmission (4-20Ma). Pulse output, upper and lower limit alarm output and other functions. This type of intelligent signal transmitter has high precision and reliability.
The working principle of High Pressure Rotameter:
The high-pressure metal tube rotameter is the force that the upper and lower ends of the float generate differential pressure to form a rising force when the measured medium passes through the conical measuring tube from bottom to top.
When the lifting force on the float is greater than the weight of the float immersed in the fluid, the float will rise. The area of the annulus will increase accordingly. The fluid velocity at the annulus will drop immediately. The differential pressure at the upper and lower ends of the float will decrease. The float is stabilized at a certain height until the lift force is equal to the weight of the float immersed in the fluid.
The height of the float position corresponds to the flow rate of the measured medium.
The float has a built-in magnet. When the float moves up and down with the medium, the magnetic field changes with the movement of the float.
a. For the local type, the rotating magnet in the local indicator is coupled with the magnetic steel in the float to rotate. At the same time, the pointer is driven to indicate the flow rate at this time through the dial.
b. For the intelligent type, the change of the magnetic field is converted into an electrical signal by a solid-state magnetic sensor in the intelligent indicator. After A/D conversion, microprocessor. D/A output, LCD liquid crystal display, to display the flow rate size and cumulative flow.

What Is Difference Between Rotameter and Flow Meter?
A rotameter is a device that measures the flow rate of liquid or gas in a closed system. It consists of a float that moves up and down in a tube, based on the fluid’s flow rate. The faster the fluid flows, the higher the float rises.
A flowmeter is a device that measures the volume of liquid or gas that flows through it. There are many different types of flowmeters, each designed to measure different types of fluids. For example, positive displacement flowmeters measure the volume of fluid that passes through them, while rotameters measure the rate of flow.
