METAL TUBE ROTAMETER- DIGITAL TYPE

Product catalog summary

Product Overview: The "FLOWTECH" Digital Metal Tube Rotameter is designed for flow measurement with a current output and totalizer. It operates on the principle of variable area, where fluid raises a float in a tapered tube, balancing the float's weight with hydraulic force. The device features a digital readout enabled by a magnetic field detection sensor and operates on battery power, eliminating the need for electrical connections.

Key Specifications:

Accuracy: ± 1.5% of Full Scale Range (FSR)
Rangeability: 10:1
Repeatability: ± 0.25% of FSR
Temperature Rating: -50 to 120°C
Pressure Rating: 80 kg/cm²
Flow Direction: Bottom to Top
End Connection: Flanged to suit customer requirements
Wetted Part: Suitable for specific liquids or gases
Mounting Position: Vertical
Indication: Digital flow rate
Transmission: 2-wire loop powered
Enclosure: Flameproof/Weatherproof
Power Supply: 9 VDC Battery / 24 V DC / 230 V AC

Performance: The rotameter provides local indication without auxiliary power, minimal pressure loss, and accurate measurement even at higher flow rates (up to 150 M³/Hr). It is suitable for low flow rates (8 LPH) and includes a default inbuilt transmitter of 4-20 mA (loop powered). The absence of a movement assembly reduces maintenance needs.

Flow and Pressure Drop: The document provides a table detailing maximum flow and pressure drop for various line sizes, with water flow rates ranging from 0.2-45 M³/Hr and air flow rates from 6-1200 NM³/Hr, depending on the line size.

Additional Information: The company, Flowtech Measuring Instruments Pvt. Ltd., is ISO 9001:2015 certified and exports to multiple countries. They offer online calibration of flowmeter sizes 40 NB to 300 NB using high accuracy ultrasonic flowmeters upon request.

DESCRIPTION “FLOWTECH” make Digital Metal Tube Rotameter is used for flow measurement where current output with totaliser is required. WORKING PRINCIPLE It operates on the principle of variable area. The fluid in the Metal Tube raised a float in the taper tube increasing the area of passage of fluid. The float moves up in proportion to the rate of flow of fluid and get stabilized when the weight of the float is balanced by the upward hydraulic force. By a magnetic coupling the inner float movement through a series of linkages and counter weight. The tube and the float combination determine the...
