Overview
The JCL-050 series Metal Tube Rotameter consists of a measuring tube and an on-site indicator. The indicator can optionally be equipped with additional electrical components, making it suitable for measuring liquids and gases. This flowmeter employs a variable area measurement principle, with a conical measuring tube and a float. The float moves freely up and down within the tube, changing the flow area as the flow rate changes. The float's vertical position is translated into a flow rate value on the indicator dial through a magnetic transmission system. It can also output signals for remote display and control.
The flowmeter is widely used in industries such as petroleum, chemical, power generation, pharmaceuticals, food, and water treatment under complex and harsh environmental conditions.
Product Features
● Suitable for Small Diameter and Low Flow Rate Measurements: Specifically designed for accurate measurement in small diameter pipes and low flow rate mediums.
● Modular Design: Easy to maintain and requires no maintenance during normal operation, reducing maintenance costs and time.
● Single-Axis Sensitive Indication with Non-Contact Magnetic Coupling: Ensures more stable signal transmission, guaranteeing the accuracy and reliability of measurement data.
● Dual-Row, Large-Screen LCD Display for Instant and Cumulative Flow: Easy to read data, with an optional backlight display for different lighting conditions.
● Intelligent Design with Power Failure Protection and Data Backup and Recovery Functions: Ensures data security and prevents data loss.
● All-Metal Construction: Shock-resistant, pressure-resistant, temperature-resistant, corrosion-resistant, suitable for harsh environments, and has a long service life.
● Low Requirement for Straight Pipe Sections: Offers greater flexibility in installation and adaptability.
● Usable in Flammable and Explosive Hazardous Areas: Designed with safety in mind to meet the requirements of hazardous environments.
● Three Power Supply Options: DC24V, AC220V, and battery power supply, catering to different usage scenarios.
