TIENet 310 Ex Ultrasonic Level Sensor

The Signature® Flow Meter uses the TIENet 310 Ex Device to provide non-contact liquid level measurement. The flow meter has built-in level-to-flow conversions that cover the majority of open channel flow measurement situations. The ultrasonic sensor is mounted over the flow stream. The flow meter measures the time interval between transmission of a sound pulse from the sensor, and receiving its echo off the surface of the liquid, to determine the level of the stream.

Signture Flow Meter

The new Isco Signature flow meter is designed for open channel flow monitoring applications. It supports flow measurement technologies including ultrasonic and bubbler. Flow can be calculated using standard open channel level-to-flow conversions, level to flow data points as well as user-defined equations, depending on the needs of the application.
Unique features provided by the Signature flow meter help to verify data integrity. It logs key events such as power outages and changes in calibration to validate data accuracy. Stored data can be easily reviewed to detect any type of data alteration.
