Frequently Asked Questions
Which level technology should I choose for chemicals with foam or vapor?
Use 80-GHz radar or guided-wave radar. Both handle foam/vapor; guided-wave excels in tight tanks/turbulence.
How do I protect pumps from dry-run?
Add the Flowline FT10 thermal flow switch interlocked to your pump control—trip at a safe low-flow setpoint.
Can I see all tanks on my phone?
Yes. Pair EchoBeam radar sensors with the LevelHub HB01 LTE-M gateway and the LevelTap™ App for dashboards and alerts.
Do these tie into SCADA/PLC?
All systems support industrial outputs: 4–20 mA, relays, and protocol options like HART/Modbus depending on model.
