SF14 Metal tube float flowmeterDetailed product description：

The SF14 metal tube float flowmeter is suitable for measuring the flow rate of small caliber and low velocity media. The product adopts a modular combination design, which is easy to maintain and maintenance free for normal use; Single axis sensitive indication and non-contact new magnetic coupling product structure make signal transmission more stable; The product features dual row, large screen LCD display for instantaneous and cumulative traffic, and can be backlit for users to easily record relevant information. The intelligent SF14 metal tube float flowmeter has power failure protection, data backup and recovery functions to ensure the accuracy and integrity of data.

The SF14 metal tube float flowmeter adopts an all metal structure, which is earthquake resistant, pressure resistant, temperature resistant, corrosion-resistant, and has a long service life. It can be used in flammable and explosive hazardous environments. The product has a short stroke and a total height of 250mm, making design and installation more convenient. At the same time, the installation of the product has lower requirements for straight pipe sections, with the first 5DN and the last 250mm.

Three power supply options available: 24VDC, 220VAC, battery powered

Selection Tips

When selecting an SF12 metal tube float flowmeter, the following parameters need to be determined in detail: pipeline diameter, measuring medium, working temperature, pressure (working or standard state), installation method (vertical or horizontal installation), display method (local pointer display or remote LCD display), power supply (24V, 220V or battery power supply), range (working or standard state), whether explosion-proof is required, and whether a matching flange is needed.
