SR41 Series Metal Tube Rotameter

• The SR41 Series Metal Tube Rotameter is an all-metal variable area flowmeter for the measurement of liquids, gases and steam under demanding process conditions.

• A fully welded metallic construction, precision-formed conical measuring tube and magnetically coupled indicator deliver stable, repeatable performance where glass or plastic rotameters are not suitable due to pressure, temperature or mechanical stress.

• SR41 is widely used in chemical, petrochemical, oil & gas, power generation, metallurgy, food & beverage, pharmaceutical, and general industrial utilities, providing reliable local indication and, when required, 4-20 mA / HART® outputs for integration into modern control systems.

• Boiler Steam Branch Indication in Power Plants

SR41 installed on individual steam distribution branches provides local indication and 4-20 mA feedback to the control system. Operators can monitor steam delivery to each user, support energy balance calculations, and quickly identify abnormal consumption or line restrictions.

• Cooling Water Monitoring for Heat-Treated Components

On closed-loop cooling circuits for furnaces, induction heaters, or quench tanks, SR41 ensures that minimum cooling water flow is maintained. Stable local indication helps protect heat-treated parts and critical equipment from overheating or thermal shock.

• Compressed Air Consumption Tracking in Workshops and Plants

Mounted on compressed-air distribution headers or key branch lines, SR41 provides immediate visual feedback on air usage. The optional transmitter output can be tied into energy management systems to detect leaks, optimize compressor loading, and allocate costs by area or production line.

• Clean Steam Flow Check in SIP/CIP Utilities

In food, beverage, and pharmaceutical facilities, SR41 serves as a robust local indicator on clean steam lines feeding SIP/CIP stations and sterilization equipment. All-metal construction and high-temperature capability make it suitable where glass rotameters would be unsafe or unreliable.

• Chemical Dosing Supervision in Water and Wastewater Treatment

Installed downstream of dosing pumps for coagulants, neutralizing agents, or conditioning chemicals, SR41 confirms that flow remains within the specified range. Local indication and optional analog output help operators fine-tune dosing rates and maintain stable treatment performance.
