Product Q&A

Q:Can this flow meter measure pulp with high fiber content?

Yes. The HL-LD Series uses low-frequency excitation technology that eliminates "pulp noise" caused by fibers. The spherical electrodes also resist coating from fibrous media.

Q:How long does the battery last?

The 3.6V lithium battery can last up to 38 months (approx. 3.8 years) depending on usage and output frequency. Battery status is displayed on the LCD screen.

Q:Can I monitor the flow data remotely?

Yes. The meter supports GPRS remote monitoring (optional). You can view real-time data from any location via a web platform or mobile app.

Q:What is the minimum pipe size available?

Our standard range starts from DN15. For smaller pipes, please contact us for customization.

Q:Is this meter suitable for abrasive slurries like iron ore or sand?

Absolutely. The meter has no moving parts, and the spherical 316L electrodes are highly resistant to abrasion. For extreme abrasion, we offer Hastelloy or Titanium electrodes.
