Basix View: a simpler approach to level sensing
By Tristan Newton, Commercial Director · 17 April 2025 · 2 min read
Basix View is a simple way to get alternative level sensing, for example for use with a Vega radar level sensing head.
But first, let's briefly go through the current options for level sensing.
- Float switches: The most common choice. They’re low cost, generally reliable, and easy to install and set up.
- Level sensing heads: These provide accurate distance readings from the sensor to the water surface. Often used in fatty wastewater tanks where float switches can foul. Typically use ultrasonic or radar technology.
- Hydrostatic sensing: The least common option. It works by measuring pressure to determine how much water is above the sensor.
Now we won't really discuss float switches as nearly everyone knows how they work (or just google it, there are a few good articles and videos).
Ultrasonic level sensing heads present several challenges. They’re often expensive—typically around £2,000 for the controller and sensing head—largely due to a proprietary connection between the two. This means both components must come from the same manufacturer, ruling out any flexibility to mix and match brands.
But cost isn’t the only concern. Setup can be complicated, with numerous parameters and nested menus that can leave site engineers frustrated. Performance is also limited in confined spaces, as ultrasonic heads generally require a tank diameter of at least 1.1 metres to deliver reliable readings.
That said, these devices do offer benefits. They’re accurate, more reliable than float switches, and often allow level readings without the need to open a manhole. However, all of these advantages are also available through alternative technologies—such as radar—that are not only more cost-effective but also easier to integrate, often providing a standard 4–20mA output.
That’s why we recommend the Basix View. It delivers the same core advantages—accurate radar-based sensing, simple level checking, and robust reliability—without the usual drawbacks. Designed to be user-friendly from the outset, it’s a solution that just works, even for first-time users.
