Signature® Flow Meter
Section 1 Introduction
The Signature Flow Meter 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 monitoring site.
The bubble line is anchored in the flow stream at the appropriate
measuring point in the weir, flume, or other open channel flow
situation. Air slowly bubbles out of the line into the flow stream.
The pressure in the bubble line is proportional to the liquid level
in the flow stream, and the flow meter measures this pressure,
sensing the liquid level.The Signature has built-in standard
level-to-flow conversions that cover the majority of open channel
flow measurement situations. Flow measurement is usually a
calculation based on a known relationship between liquid level
and flow rate. Additionally, the Signature can calculate flow
using standard open channel level-to-flow and area-velocity con-
versions, as well as equations, or data points, depending upon the
measurement device(s) attached to the meter and the program
specified by the user.
Note
Recent enhancements have been made to the Signature Flow
Meter. Many of these features are standard for all new Signa-
ture units which are identifiable by the serial label mounted on
the bottom of the unit (PN 60-4304-065).

1.2 Data Integrity What makes the Signature Flow Meter unique is its ability to
verify data integrity. This is accomplished by logging four special
event data types that cannot be altered, and are designed to alert
the user to any trends or anomalies, and to assess compliance.
This data can be downloaded from the flow meter and observed
in tabular or graphical format alongside regular site data, using
Flowlink software (see Section 2.10 Signature Data in Flowlink).
The data can also be downloaded onto a flash drive via the
micro-USB assembly on the front panel of the flow meter, then
imported into a spreadsheet or other viewing application (refer to
Section 2.9 USB Options for more information).
The four event data types are:
Program Report – Tracks changes to the Signature Flow Meter
configuration
Summary Report – Documents summaries of data measure-
ments (e.g., Min/Max/Avg)
Diagnostic Report – Tracks results from diagnostic tests
History Report – Tracks user and meter events (e.g., level
adjustments, data push, etc.)
1.3 Security The Signature Flow Meter can be secured shut with a padlock
with the hasp on the right side of the housing (refer to
Figure 1-3). The program settings and recorded data can be pro-
tected by a user-selected passcode (refer to Section 2.8.2 Set New
Passcode.
1.4 Compatible
Equipment
The Signature Flow Meter can interface with a variety of mea-
surement devices and other system components, depending on
site requirements.
Measurement devices for flow and water quality can be con-
nected to the same Signature Flow Meter and run simultane-
ously with TIENet®connectivity (up to nine TIENet devices).
The flow meter can also communicate with an optional Teledyne
Isco wastewater sampler and rain gauges.
For descriptions of interfacing and parameter sensing TIENet
devices, refer to Section 5 Equipment Options. Each external
TIENet device comes with its own user manual.
The Signature is capable of receiving data from devices using
Modbus ASCII or Modbus RTU protocol.
A variety of application-specific accessories are available from
Teledyne Isco. Refer to Appendix B Options and Accessories for a
complete list with ordering information.
A basic Signature system has one or more TIENet devices for
flow and/or parameter measurement connected to the Signature
Flow Meter (up to nine TIENet devices at once). Other configura-
tions may include an enclosure and additional internal or
external devices, including analog output cards, analog input
cards, contact output cards, a modem, up to two SDI-12 inputs,
and Modbus devices.
