PDA based correlator
The AQUASCAN 900 PDA correlator converts a Personal Digital Assistant (PDA) into a flexible, powerful and extremely portable high-precision leak detection and pinpointing instrument.

Multi point system allows correlation between any number of sensors
The AQUASCAN 900 is available as a dual, triple or multi sensor system, providing correlation between any number of sensors.

Automatic velocity check
An innovative feature allows automatic velocity check where pipe material and diameter may be unknown.

Ultra compact sensors with built-in transceiver
Using the latest, state-of-the-art technology, the size and weight has been reduced to a minimum. The sensor/accelerometer and transmitter/receiver are combined into a single, very compact sensor with built-in transceiver, meaning no separate transmitter, cable, or sensor/accelerometer is required – simply place the combined transmitting sensor directly onto the valve spindle or chosen point of connection with the pipeline.

Fully digital system offers highest performance and precision on all pipe materials
The AQUASCAN 900 is fully digital and offers the highest performance and precision on all pipe materials without the known disadvantages of analogue radio transmission.

User-friendly Palm OS based operating software
The AQUASCAN 900 Palm OS based operating software allows easy entry of pipe data and displays correlation results in a very user-friendly format.

Automatic filter and parameter setting
The PDA software also features fully automatic or user-selectable filter and parameter settings, full FFT and coherence analysis and individual sensor sound monitoring and signal strength bars.

Enter pipe details at site, or later
Additionally, pipe details can be entered at site or entered/corrected later for a fully revised leak position.

Powerful transceiver for interactive communication
The AQUASCAN 900 offers another innovation in correlation technology: For the first time, the sensors are equipped with a transceiver allowing the user interactive communication with the sensor for optimising the adjustment of the measurement settings in the sensor.

Remote listening to any sensor
With AQUASCAN 900 the operator can also perform vital leak ‘sounding’ by simply selecting any sensor via the PDA. The operator can then listen to all noise activity picked up by each sensor entirely remotely and in true wireless digital sound quality.

Large memory of correlation files and direct printout from PDA
All correlation files and leak positions can be printed out directly from the PDA, or can easily be stored and/or transferred to a PC using widely available Memory Expansion Cards inserted into the PDA.
