Signature flowmeter

Flexible, configurable flow meter for permanent discharge compliance monitoring

The Signature is a configurable water flow meter for permanent discharge compliance monitoring of water flow rate, wastewater flow rate and stormwater flow rate.

Signature flow meters are designed for open channel flow monitoring. The flow meter supports water flow meter technologies including bubbler, non-contact laser area velocity, submerged Doppler ultrasonic area velocity, and ultrasonic. The Signature can calculate flow using standard open channel level-to-flow and area velocity conversions, as well as user-defined equations, level to area data points, or level to flow data points, depending on the application need.

Signature flow meters have unique features to verify data integrity. The flow meter logs key events, such as changes in calibration and power outages, to validate data accuracy. Data can be easily reviewed to detect any type of data alteration. With multiple smart interface options and multi-parameter logging (such as pH), Signature flow meters provide a common platform for control action, reporting, and communication of water flow, wastewater flow and stormwater flow..

Multiple flow technologies are available, so you can select the best flow technology for the measurement site and channel conditions. Available technologies are: bubbler, ultrasonic, continuous wave area velocity, and non-contacting LaserFlow® velocity​.

​​Frequently Asked Questions​

What is a flow meter us​ed for?

A flow meter measures the rate of speed of a liquid or gas through a pipe or channel by reading input from a variety of available flow rate instruments. Unlike water meters on a home or business, flow meters are generally used in applications to measure the flow of liquid through a larger pipe or open channel. By considering the size of the pipe or channel, the volume of liquid and the flow rate, you can determine how much liquid or gas is flowing through a given point, in a given amount of time. The Teledyne ISCO Signature flowmeter, for example, is designed for open channel flow monitoring applications.

What is the most co​mmon flow meter?

A differential pressure flow meter is the most common. They are a form of mechanical flow meters that measure pressure flow across a pipe restriction. While fairly accurate, they have limitations. For example, they aren’t applicable to open channel applications and in many instances are not as accurate as other available methods.

What is the difference between a flow m​eter and a flow gauge?

Flow meters ​​measure the flow rate in a pipe or open channel. It can be used for quality control, rules and regulations compliance, and billing purposes. A flow gauge measures the flow pressure in a pipe. A flow gauge monitors the water pressure into your house. A water meter determines how much water you use each month.​
