rotor meter flow meter for liquid flow

A metal tube float rotameter is a device that measures the volumetric flow rate of fluid in a closed tube.

Rotor Meter, or rotary flowmeter, is also called metal float flowmeter. The metal or glass float flowmeter belongs to a class of meters called variable area flowmeters, which measure the flow rate by allowing the cross-sectional area the fluid travels through to vary, causing a measurable effect.

The rotor meter can also be called a ratary meter, and the rotor meter is used in various fields.  

Main technical parameters:

Pressure: 1.6MPA

Material: 316L

Accuracy: 1.5class

Indicator : M10 indicator (light blue) LCD display 4~20mA output instantaneous and cumulative flow and HART with backlight

Flange standard: HG20592-2009  DN:15 PN1.6RF

Installation method: horizontal installation (standard) (left in and right out)

Protection level: IP67

Electrical interface: 1/2NPT

The Rotor Flowmeter is used with a small pipe diameter and a low flow rate. Commonly used instrument caliber 40-50mm below, the smallest caliber to 1.5-4mm. Suitable for measuring low flow rate, small flow rate and liquid.

Advantages

A rotameter requires no external power or fuel, it uses only the inherent properties of the fluid, together with gravity, to measure the flow rate. 

A rotameter is also a relatively simple device that can be mass produced from cheap materials, allowing for its widespread use.

Since the flow passage area increases as the float moves up the tube, the gradient is approximately linear.

Clear glass is used, which is highly resistant to thermal shock and chemical action.
