## What is Quadbeam?

Quadbeam is the official companion app for configuring and monitoring Quadbeam Technologies suspended-solids and turbidity sensors over Bluetooth Low Energy.

Connect your phone directly to a Bluetooth-equipped Quadbeam sensor and take full control on site — no laptop, no cables, no separate handset. See live measurements, manage calibration, and set up your analogue outputs and relays in minutes.

KEY FEATURES

• Direct Bluetooth connection
Scan for and connect straight to your Quadbeam (QB) sensor. Pull to refresh to find nearby devices.

• Live readings
View real-time sensor output as it happens, with adjustable smoothing to stabilise readings in dynamic process conditions.

• Multi-point calibration
Set and review calibration points, with options to extrapolate above and below the table and force values where needed.

• Outputs & control
Configure your 4 mA and 20 mA output points and review live current and input status to match your control system.

• Flexible units
Work in the units that suit your process, including mg/l, g/l, ppm, %, NTU and FNU, with adjustable decimal places.

• Multiple sensors
Manage more than one sensor and switch between them from a single, clear interface.

Quadbeam is built for water and wastewater treatment, food and beverage, mining, and other process applications that depend on accurate suspended-solids and turbidity measurement.

A compatible Bluetooth-enabled Quadbeam sensor is required to connect and configure.
