Radar Flowmeters





Radar Flowmeter

Flow+Level+Surface velocity measurement

Integrated tilt sensor

Compact, light and easy to mount

Nice choice for open water measurement


Parameters for details

The F40 radar flowmeter integrates a P40 level sensor and a V20 surface velocity sensor, which enables F40 to measure real time water flow. It uses standard Modbus/RS485 protocol and can be operated in a standalone mode, with optional telemetry systems or interfaced directly to a third party data logger or PC.

The radar flowmeter is for non-contact flow measurement at surface water locations. It uses impulse radar technology to determine the water level and velocity. This energy-efficient, non-contact measurement method means the device operates with no effect from temperature gradients, water pollution or sediment load and ensures exact measurements.


Features

  • Flow, level and velocity outputs
  • Non-contact measurement
  • Integrated tilt sensor
  • Uses rotatable swivel and easy mounting
  • Sensor is away from the water, making the installation safer to achieve
  • Standard interfaces for communication with data loggers and other devices
  • Extremely low power consumption
  • Anti polarity protection
  • Flat antenna means that insect and spider infestation is not a problem
  • Compact and solid design – long sensor life with minimal maintenance
  • RS-485 interface – allows a connection cable length of up to 1,000 m, allowing data logger and power source to be situated further away
  • Wide range of power supply from 7-32 V (typically 12 / 24 V) – allows differing power supplies such as solar panel, battery or grid
