The Signet 2537 Flow Sensor is the next generation in fluid measurement technology from the inventor of the original paddlewheel flowmeter. This sensor is an enhancement on what is already an industry standard. It has the added functionality of various output options including flow switch, pulse divider, digital (S3L) or 4 to 20 mA. Additionally, it offers low flow, low power and high resolution and can be configured on-site directly through the built-in user interface.
Fields of Application:
The Signet 8150 Battery Operated Flow Totalizer is compatible with the Signet 515 and 525 flow sensors, and will provide years of dependable operation. The large digital display indicates flow rate and totalized flow volume simultaneously. One of the three totalizers is resettable from the front panel or a remote location, while the second resettable totalizer can only be reset by entering a user-selectable security code. Meanwhile, the third is a permanent non-resettable totalizer.
Simple to install with time-honored reliable performance, Signet Model 515 Rotor-X Paddlewheel Flow Sensors are highly repeatable, rugged sensors that offer exceptional value with little or no maintenance. The output signal of the Model 515 is a sinusoidal frequency capable of driving a self-powered flowmeter (Model 5090). The wide dynamic flow range of 0.3 to 6 m/s (1 to 20 ft/s) allows the sensor to measure liquid flow rates in full pipes and can be used in low pressure systems.
The Signet Model 515 sensors are offered in a variety of materials for a wide range of pipe sizes and insertion configurations. The many material choices, including PP and PVDF, make this model highly versatile and chemically-compatible to many liquid process solutions. Sensors can be installed in up to DN900 (36 in.) pipes using Signet's comprehensive line of custom fittings. These custom fittings, which include tees, saddles, and weldolets, set the sensor to the proper insertion depth into the process flow. The sensors are also offered in configurations for wet-tap requirements.
The GF Signet 9900 Transmitter provides a single channel interface for many different parameters including Flow, pH/ORP, Conductivity/Resistivity, Salinity, Pressure, Temperature, Level and other sensors that output a 4 to 20 mA signal. The extra large (3.90" x 3.90") auto-sensing backlit display features "at-a-glance" visibility that can be viewed at 4-5 times the distance over traditional transmitters. The highly illuminated display and large characters reduce the risk of misreading or misinterpreting the displayed values. The display shows separate lines for units, main and secondary measurements as well as a "dial-type" digital bar graph.The 9900 is offered in both panel or field mount versions. Both configurations can run on 12 to 32 VDC power (24 VDC nominal). The 9900 can also be loop powered with compatible sensors.Designed for complete flexibility, plug-in modules allow the unit to easily adapt to meet changing customer needs. Optional modules include Relay, Direct Conductivity/Resistivity, H COMM and a PC COMM configuration tool. The unit can be used with default values for quick and easy programming or can be customized with labeling, adjustable minimum and maximum dial settings, and unit and decimal measurement choices.
This is a required accessory for the 9900 field mount transmitter for integral mounting on GF Signet 515 Series sensors
Optional adapter for 8050 Universal and 8051 Integral mounts.
GF Signet installation fittings are designed to secure insertion style flow sensors into position and control the position of paddlewheels and electrodes in relation to the dimensions of the pipe. Use the proper fitting for your system to obtain the best results.
Metalex fittings are only for use with Metalex flow sensors.
Consult the fittings' datasheet to insure you select a fitting appropriate to the installation.

The GF Signet H COMM Module enables communication between the 9900 transmitter and a HART®-enabled device. The HART (Highway Addressable Remote Transducer) Protocol superimposes digital signals on top of the 4 to 20 mA analog signal.Advantages:Allows communication between the 9900 Transmitter and a HART® enabled deviceAllows access to primary and secondary measurements remotelyAllows user to remotely adjust the 4 and 20 mA settings
The GF Signet 9900 Relay Module adds two programmable dry-contact relays. The open collector output in the 9900 base unit uses the Relay 1 setting. The Relay Module is assigned to relays 2 and 3 in the menus.
