Bimetallic Tube Rotameter, Vertical, 4-20ma, Explosion-Proof, Digital Display, Pointer Type

The bimetallic rotor flowmeter is a volumetric flowmeter. Its working principle is based on the energy of the fluid itself to drive the measuring element, and the flow value is directly displayed through mechanical coupling.

Product Features

High Precision and Good Repeatability: As a volumetric flowmeter, it has extremely high measurement accuracy, especially in the measurement of viscous media. The accuracy is usually ±0.5% or even higher.
Wide Range Ratio: It has a wide measurement range and can maintain accuracy over a large range of flow rate changes (range ratio up to 10:1).
Unaffected by Fluid Properties: Its measurement principle is based on volume, so the measurement results are basically unaffected by changes in fluid temperature, pressure, density, and viscosity (of course, extreme changes will have an impact, but it is much smaller than other types of flowmeters).
Direct Reading, No External Power Required: It uses a pure mechanical structure for indication and can work without power supply, making it very suitable for on-site observation and highly reliable and safe.
Robust Structure and High Reliability: It has few internal moving parts, a sturdy design, and a long service life.

Application fields

Petrochemical industry: Flow measurement of crude oil, refined oil, lubricating oil, and asphalt.
Chemical industry: Measurement of various resins, polymers, solvents, and chemical raw materials.
Food : Syrup, edible oil, chocolate, dairy products, etc.
Shipping: Fuel oil filling machines, measurement of oil and water in the bilge.

Brief comparison with other flowmeters

Compared with vortex flowmeters: The bimetallic rotor is not afraid of vibration and has higher accuracy, but it has greater pressure loss and is more demanding on the cleanliness of the medium.
Compared with electromagnetic flowmeters: The bimetallic rotor can measure non-conductive liquids (such as oil products), but electromagnetic flowmeters have no pressure loss and are more tolerant of dirty media.
Compared with oval gear flowmeters: Both are volumetric and have similar principles. The bimetallic rotor (usually referring to the helical rotor) can handle larger flow rates, operates more smoothly, and generates less vibration and noise.

Summary

The bimetallic rotor flowmeter is a mechanically operated flowmeter that is technologically mature, highly accurate, and reliable. It plays a significant role in trade settlement and process control for medium to high viscosity, clean liquids. Its core advantages lie in being "direct, precise, and self-sufficient", but it is crucial to remember the key requirement of "pre-filtering" when using it.
