The technology of RESOTECH includes patented innovative and cost-effective sensors and data loggers that enable water companies to manage their distribution networks significantly more efficiently. This leads to reduced energy costs and emissions while optimising the use of water resources. The sensors from RESOTECH are designed for flexibility, with step-by-step implementation capabilities and scalability in quantity. They can operate independently but can also be integrated with existing measurement and control systems, including communication infrastructures. The Resotech sensor measures flow and, optionally, pressure and temperature at the same connection point.

The Resotech sensor is available as a Product-as-a-Service solution. This approach is particularly attractive as it reduces operational risks by including expert maintenance and a comprehensive first-class warranty. Additionally, this solution supports sustainable business practices through a circular model, allowing customers to return the product to Resotech for recycling and reuse if necessary.

Main Applications:

• Pressure, flow, and temperature monitoring

• Low-cost bi-directional flow measurement from DN 80 to DN 2000

• Option under development (not yet ready: conductivity measurement) for quality

Unique Benefits:

• "Low power" sensor; can be powered by a 3.6V DC battery (can therefore be placed anywhere)

• Low installation costs with up to 90% savings compared to “in-line” meters

• Cost of the meter independent of the pipe diameter in which it is installed

• No limitations due to the physical/chemical properties of the fluid and electromagnetic interference (grounding is not required)

• Can be connected to all telemetry systems: multiple interface/communication options (RS-485 programming interface (Modbus), pulse output, LoRa, (NB IoT or other interfaces possible))

• High reliability: proven performance in leak detection systems in Italy (Pisa region). (see video)

Specifications:

• Bi-directional Flowmeter (Load cell technology)

• Measurement range of 0.1 to 1.8 m/s

• Accuracy better than 2% when reading in 70% of the measurement range

• Open collector outputs for RTU (speed and flow direction)

• RS-485 programming interface

• Insertion without interrupting the water flow

• Housing protection rated at IP68

• Housing materials: stainless steel AISI316

• Pipe diameter range: DN 80 to DN 2000

• Nominal pressure PN16

• Power supply: 3.6V DC (lithium battery)

• Minimum sampling period: 2 seconds

• Operating/Storage temperature: -10 to 45°C / -20 to 60°C
