Introduction

INTRODUCTION
Flo-tech turbine flow sensors measure the flow rate of hydraulic fluid and compatible liquids. Built to withstand rigorous hydraulic applications, these flow sensors are available in anodized aluminum and zinc plated Stressproof® steel bodies. Port types vary by body material, but include a choice of SAE, BSPP, Code 61 and Code 62, 4-bolt flanged options.
Typical applications for the turbine flow sensors include:
• Fluid characteristic measurement on test stands
• Stationary hydraulic system monitoring
• Feedback for hydraulic system control
• Advance warning of impending component failure
• Mobile hydraulic system diagnosis Flo-tech offers four different flow sensor models. Each of these models is available in a wide selection of flow ranges and
port sizes.

Operating Principle

OPERATING PRINCIPLE
1 Housing 6 Signal Converter (analog output) 2 Turbine Rotor 7 Pressure Port Adapter 3 Rotor Supports 8 Temperature Port Adapter 4 Lock Nut 9 Retaining Rings 5 Magnetic Pickup (frequency output)
Turbine flow sensors measure the flow rate of hydraulic fluid and compatible liquids. As fluid flows through the sensor it turns the turbine rotor, and as the turbine blades pass the magnetic pickup a frequency signal is generated. This frequency signal is proportional to the flow rate and can be transmitted to Flo-tech’s digital displays or converted to an analog output. Optional sensors allow measurement of pressure and temperature.

INSTALLATION

THIS PRODUCT SHOULD BE INSTALLED AND SERVICED BY TECHNICALLY QUALIFIED PERSONNEL TRAINED IN MAINTAINING INDUSTRIAL CLASS FLOW INSTRUMENTATION AND PROCESSING EQUIPMENT.
READ INSTRUCTIONS THOROUGHLY BEFORE INSTALLING THE FLOW SENSOR. IF YOU HAVE ANY QUESTIONS REGARDING PRODUCT INSTALLATION OR MAINTENANCE, CALL YOUR LOCAL SUPPLIER OR THE FACTORY FOR MORE INFORMATION.
WARNING
DO NOT USE MALE PIPE THREADS (NPT) INTO SAE STRAIGHT THREAD PORTS. USING MALE PIPE THREADS (NPTF) WITH A FLOW SENSOR POSSESSING SAE STRAIGHT THREAD O-RING PORTS WILL NOT CREATE A PROPER SEAL AND IS POTENTIALLY DANGEROUS. PIPE THREADS INSERTED INTO AN SAE STRAIGHT THREAD PORT ONLY ALLOW THE ENGAGEMENT OF ONE OR TWO THREADS. NO AMOUNT OF TIGHTENING OR THREAD SEAL WILL STOP THE LEAKING OR MAKE THE INSTALLATION SAFE. FAILURE TO FOLLOW THESE INSTRUCTIONS COULD RESULT IN SERIOUS PERSONAL INJURY OR DEATH AND/OR DAMAGE TO THE EQUIPMENT.

Installation

Installation Recommendations

The in-line flow sensor is a simple device to install. However, the following measures are recommended for reliable, trouble-free operation:
1. Provide at least 10 port diameters of upstream straight pipe with no obstructions to the ow sensor and at least 5 diameters of downstream pipe. The pipe should be of the same diameter as the nominal port size.
1" PORT
(25.4 mm)
END VIEW
10 PORT DIAMETERS
10" (254 mm)
IN
5 PORT DIAMETERS
5" (127 mm)
Example:
An FSC-1000 has a 1 in. (25.4 mm) port. The unobstructed upstream length should be at least 10 in. (254 mm) and the downstream length should be at least 5 in. (127 mm).
2. Choose a position for the ow sensor that is not at the lowest level in the system. Placing the ow sensor at a higher elevation in the system will avoid collection of debris, sediment and dirt in the ow sensor.
3. Use a lter. All applications should be ltered to at least 40 micron.
4. Do not install a ow sensor directly in-line with the outlet of a pump, as pressure pulsations can react with the turbine. Install the sensor after another component, observing the 10 port diameter rule.
5. Do not adjust the magnetic pickup on the ow sensor. This is calibrated at the factory. Further adjustment will cause a decrease in performance or damage to the sensor.
6. Do not exceed the working temperature range of –4…300° F (–20…150° C). Higher temperatures will damage the magnetic pickup and lower temperatures will limit the rotation of the turbine.
