TECHNOLOGICAL EVOLUTION WITH IOT

AQUALOG PQ EVO: the RTU that handles every aspect of control and management of the water network, with monitoring and control of the pressure, flow rate and levels.

You can configure the PQ Evo to suit your needs.

AQUALOG PQ EVO is a multi-parameter IoT sensor that can monitor the pressure, flow rate and levels in areas that are difficult to access and where electricity is not available.

AQUALOG PQ EVO is battery operated and designed to require minimal energy.

  • Low power, at least 6 years battery life
  • IP68 protection
  • 4-20mA signals
  • "Discovery" mode to detect pressure surges Acquisition and transmission of data from the critical point (Real Time Critical Point)
  • PRV or inverter control with the modes:
    • Down-Stream PRV, Fixed Pressure
    • Day/Night
    • Flow Modulation
    • RTCP System: adjustment in relation to the pressure value at the critical point
    • RTCP System by Machine Learning Communication with local devices
  • Prevention of flooding with measurement of the level in spillways (The Wave)
  • Flow level for open channels (Level-X)
  • LoRaWAN Modem and NB-IoT Modem Connection to the control centre with GSM/GPRS/3G/4G communication

DATA ACQUISITION

Basic acquisition time: 1” Basic storage time: 1’ - 1h

Maximum number of variables that can be acquired: 8 Maximum number of samples stored: 250000

MONITORING IN REAL TIME

IoT - Cloud technology with LoRaWAN and NB-IoT Modem* "Always on" applications with external power supply
Test investigation

"DISCOVERY" MODE HIGH FREQUENCY DATA ACQUISITION
(FOR INVESTIGATION OF PRESSURE SURGES)

High frequency data acquisition software module with sampling up to 125 times per second. Each pressure surge that is detected is saved and recordedfor up to 25 seconds.

Up to 100 pressure surges can be stored on the device.

The data can be saved in a CSV file (Use of this function reduces the battery life).

Discovery mode requires use of the piezoresistive sensor.

METERS

2 - Range: 32 bit. - Calculation of total consumption and of the flow rate

CALCULATION OF THE FLOW RATE FOR OPEN CHANNELS*

Calculation of the flow rate for Venturi and Parshall type open channels and Bazin and Thomson type weirs
• level/flow rate for small open channels for the drainage of rainwater
• flow rates of sources with Bazin type weirs or weirs of other geometrical shape
• duration of overflow • overflow detection
