Signature Flow Meter
- Unique Data Verification Logs changes in calibration and power outages to validate data accuracy
- Flow Measurement Technology Supports flow measurement technologies including bubbler and ultrasonic
Overview
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.

Options and Accessories
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.
TIENet 330 Bubbler module
The Signature® Flowmeter is designed for open channel flow monitoring applications using any combination of flow and parameter measurement technologies and sampling, depending on what is required at the measurement site. The bubbler level sensor can be used in almost any open channel flow application and performance is unaffected by steam or foam on the surface of the water. The bubble line is anchored in the flow stream at the appropriate measuring point in the weir, flume, or other open channel flow situation. The pressure in the bubble line is proportional to the liquid level in the flow stream sensing the liquid level.
TIENet 350 Area Velocity Sensor
The Teledyne Isco TIENet 350 Area Velocity Sensor measures flow stream average area velocity and liquid level. The Signature® Flow Meter uses this information to calculate the flow rate and total flow of the stream. To operate with the 350 sensor, the Signature requires software version 1.18 or later. The 350 sensor is mounted in the flow stream, normally at the bottom of the channel. It measures average velocity using continuous ultrasonic sound waves to produce a Doppler effect, in which the frequency of a wave (such as sound) passed between two bodies is relative to the motion of each. As they move nearer to each other, the frequency increases; as they move apart, the frequency decreases. The 350 sensor measures liquid level using an internal differential pressure transducer.
