G2-FLOW Flow Monitor

The NexSens G2-FLOW is a fully integrated water flow measurement system. An integral battery pack and cellular system provide real-time data and notifications.


Area Velocity or Pressure Only Flow

Simple integration and automatic sensor detection of Pipeline PSA-AV area velocity or PT-500 pressure transducer

Real-Time Updates

An embedded cellular modem provides live, customizable weather and water quality notifications on a mobile device or computer.

Fully Featured Design

The G2-FLOW incorporates logger, transmitter, battery power, and online data management into a streamlined design. All equipment is housed in a compact IP69 waterproof enclosure. A customer simply needs to select and connect their PSA-AV or PT-500 sensor and everything is ready to work.
