4-20mA Precise DN150 Metal Rotameter Low Maintenance

Precise Metal Tube Rotameter Widely Use DN15-DN150 Low Maintenance

The Precise DN150 Metal Tube Rotameter is a heavy-duty, variable area flow meter engineered for high-volume industrial applications. Designed for DN150 (6-inch) pipelines, this instrument combines the ruggedness of an all-metal construction with the intelligence of a 4-20mA digital transmitter.

Whether you are measuring water, industrial gases, or corrosive liquids, this rotameter provides a stable, accurate, and low-maintenance flow monitoring solution that excels where glass-tube meters cannot.

Features

1. Wetted parts material are optional: SS304, SS316L, FEP, Hastelloy C, Titanium.
2. Adopt advanced magnetic coupling system design, improve the accuracy and stability.
3. The upper row displays the instantaneous flow, the lower row displays the total flow.
4. For the digital LCD display type, the flow range of the instantaneous flow can be corrected onsite based on the different measuring medium.
