When choosing equipment to measure the volume of the flowing medium, engineers prefer devices capable of operating in extreme conditions. The metal rotameter IZMERKON RM 470 is specially designed for operation at high pressures and temperatures. The flowmeter provides accurate data display even when working with aggressive chemical substances.
Features of the RM 470 Model
The main advantage of the IZMERKON RM 470 lies in:
- Magnetic data transmission: Since the housing is made of metal, the float position is transmitted to the indicator via magnetic coupling, eliminating the risk of leaks.
- Operation with aggressive media: The possibility of manufacturing the flow part from stainless steel SS316L, titanium, Hastelloy, or using FEP (fluoroplastic) lining allows this rotameter to be used for liquids with acids and alkalis.
- Installation versatility: The device supports both vertical and horizontal installation, significantly simplifying pipeline system design.
- Electronics: Unlike simple mechanical models, this electronic rotameter can be equipped with an LCD display and transmit a 4-20 mA signal via the HART protocol.

General Information about the Device
IZMERKON RM 470 is an industrial rotameter-type flowmeter used in the chemical, oil and gas, food, pharmaceutical industries, and automotive manufacturing. It is designed to measure the flow rate and total volume of gases and liquids. The device offers the highest level of reliability. If you want to buy a rotameter for outdoor use or in unheated premises, the RM 470 is an optimal choice due to its wide operating temperature range.
Operating Principle
The device operates based on the law of changing the cross-sectional area at a constant pressure drop. Inside the conical metal tube is a float. When the medium starts moving from bottom to top, it lifts the float. The higher the flow velocity, the higher the float rises, increasing the annular gap between itself and the tube walls.
Inside the float is a powerful magnet, whose field is detected by a sensor in the indication unit. Thus, the flow rotameter converts the physical movement of the float into understandable digital or analog values without compromising the system's tightness.
Applications of the IZMERKON RM 470 Device
Measurement of Water and Liquid Parameters
The water rotameter is often used in water treatment systems and industrial equipment cooling. With an accuracy of up to ±1.0%, the device allows strict adherence to technological regulations. It is effective for both pure demineralized water and oils or alcohols.
Measurement of Gas Media
In energy and mechanical engineering, rotameters for gases are highly demanded. The RM 470 model handles accounting for air, nitrogen, and other technical gases excellently.
- Argon rotameter: indispensable for controlling the supply of shielding gas in welding processes and metallurgy.
- Oxygen rotameter: used in heavy industry to intensify combustion and metal cutting processes.
- Gas rotameter: used for monitoring flare systems and fuel supply to burners.
