High Visibility Rotors.

Determined to provide you with the most versatile line of flow sensors available, we’ve continued a non-stop refinement process for the entire RotorFlow

®

Series. GEMS new generation of RotorFlow

®

sensors, the RF-2500 Series, have been totally re-engineered with a one piece composite rotor, stronger unibody construction, ceramic shaft and better sealing. The results are greater durability with broader chemical, temperature and pressure capabilities.

7/16˝ Hex Hub

Today’s RotorFlow Series is state-of-the-art and offers more options, better performance and durability than ever before...all at an affordable price geared for high volume, OEM applications.

Select the RotorFlow sensor that is right for your application by choosing one of our three distinct configurations. You’ll find details on each of these configurations inside.

RotorFlow Switch Types

For specific flow setpoint switching, RotorFlow RFS type switches are one of the most reliable flow switches available. Setpoints are fully adjustable over the specified flow range. The dynamic operation of the rotor guards against jamming and false actuation.

RotorFlow Output Types

For flow rate monitoring or metering applications. RotorFlow RFO

Type sensors provide a pulsed DC voltage output that is proportional to the rate of flow. The operating range of 4.5 to 24 VDC pulsed output is easily integrated into most digital logic units. RFA Type RotorFlow sensors provide a continuous 0-10 VDC analog output.

RotorFlow Indicator Types

For those who want simple visual confirmation of flow, RotorFlow

RFI indicators provide the durable, low-cost answer. A bright, orange spinning rotor provides visual flow confirmation at a glance.

Flow Set Point Switching – RFS Types

Combines visual confirmation of flow with dynamic, electronic switch operation

Easy, adjustable switch point calibration: a local LED signals when set point is reached

RotorFlow

®

Switches build an extra level of reliability and protection into your equipment. By principle of operation, the rotor cannot be deceived into indicating a positive flow situation when no flow actually exists. Once set to a desired actuation point, RotorFlow will switch to a “no-flow” condition should the rotor stop for any reason.

RFS TYPE

Switch Set Point Calibration With LED Signal (RFS Type)

With the unit installed in the line and power supplied, complete the following steps to calibrate switch actuation point with proper flow rate. A small flat-blade screwdriver is the only tool required.

1. Adjust liquid flow in the line to the rate at which switch actuation is desired.

2. Insert screwdriver into opening on backside of housing and fit blade into the potentiometer adjustment screw inside.

3. If LED is not illuminated, slowly turn screwdriver counterclockwise and stop as soon as LED illuminates.

4. If LED is illuminated, turn screwdriver clockwise until LED light goes out. Then, slowly turn screwdriver counterclockwise and stop as soon as LED illuminates.

Operating Principle

HALL EFFECT SENSOR

SENDS A VOLTAGE PULSE

WITH EACH PASS OF

MAGNETIC FIELD

MAGNETIZED ROTOR

FLOW OUT FLOW IN

1. As liquid passes through the RotorFlow body, the magnetic rotor spins at a rate proportional to flow. This causes a series of magnetic fields (the rotor vanes) to excite the Hall Effect sensor, producing a series of voltage pulses.

2. The output pulses (RFO) are at the same voltage level as the input (4.5 - 24 VDC) with a frequency proportional to the flow rate. The output signal can be utilized by digital rate meters totalizers or other electronic controllers. RFA Type analog sensors condition the output signal to 0-10 VDC.

3. RotorFlow Indicators may be mounted with flow entering either port. Performance is optimized by positioning ports at the top of the unit, in a horizontal plane.

RFA/RFI TYPES

Visual Indicators – RFI Types

This is RotorFlow in its most basic form — a bright orange rotor turning with fluid flow. Simple, direct and reliable. Flow rate is estimated, or simply confirmed, by viewing the speed of the turning rotor. Either port may be used for incoming flow, and bayonet mounting lens is easily removed for quick cleanout. RFI Type RotorFlow sensors are easy to see, easy to install and easy to afford.

Typical Applications

• Visual flow confirmation on heat exchangers • Plastic injection molding equipment

Operating Principle

1. As liquid passes through the RotorFlow body, the rotor spins at a rate proportional to flow.

2. RotorFlow Indicators may be mounted with flow entering either port. At low flow rates, performance is optimized by positioning ports at the top of the unit, in a horizontal plane.

Easy Installation and Maintenance

A proper installation will enhance RotorFlow sensor performance. Install using standard pipe fitting tools; horizontal fluid lines are recommended. For further installation and maintenance recommendations, refer to one of the following instruction bulletins: RFO Types–Part Number 157258; RFI Types–Part Number

157259; RFS Types–Part Number 157261.

Since their function is to monitor dynamic fluid flow, naturally the rotor will react to turbulence, pulsation, entrained air, and other flow anomalies induced in the flow stream by other process hardware. For optimum performance, install RotorFlow units where nominal flow conditions exist with ports located at the top. Incoming flow may be placed to either port; a minimum of 8 inches (20 cm) of straight pipe on the inlet side is required. When operating in the low flow range, the supplied Low Flow Adapter must be installed in the incoming port.

Panel Mounting

Plastic Bodies. Two (2) mounting ears are provided at the body center line to receive #8 self-tapping screws to accommodate panel mounting of the plastic

RotorFlow units. Note: ANSI T type 23 self-tapping screws are recommended. They may be replaced with standard machine screws if re-installation should be required.

Brass and Stainless Steel Bodies. Two (2) mounting holes are provided on the body centerline, as shown below. #8-32UNC-2B screws are required for mounting.

2.50˝ (63.5 mm)

2.50˝ (63.5 mm)

Except for straight-thread versions, RotorFlow sensors connect to piping via NPT mating thread forms.. The use of an appropriate thread sealant is necessary to assure a leak-tight connection. Permatex “No More Leaks

®

” or 2 wraps of Teflon

®

tape are the only sealants recommended for GEMS flow sensors. Straight-thread versions require an O-ring for sealing.

150 micron filtration is recommended. However, should foreign particles enter the

RotorFlow sensor, accumulation is easily cleared by removing the lens from the body.

The lens is removed by turning its 7/16˝ hex center hub 45° counter-clockwise with a standard socket wrench. To reinstall the lens, simply reverse the process. Pressure must be relieved from the system prior to sensor clean-out. O-rings should be lubricated prior to re-assembly.

Low Flow Applications

A low flow adapter is supplied with all Rotorflow units. It is used to produce accurate response at low flow rates. Install the adapter, as shown above, in the port selected for incoming flow.

Economical Flow-Rate Sensors

 Low Cost Plus High Accuracy ±3% of Reading

 Measures Low Liquid Flow Rates of .1 to 8 GPM

 Lightweight Plastic Design Enables Mounting in any Position

Gems Hall Effect turbine flow rate sensor is ideal for OEM applications involving low flow liquid monitoring. The low cost coupled with 1/2% repeatability makes it an ideal candidate for replacing dispensing timer systems. Unlike existing timing systems, turbine technology is not influenced by changes in system pressure caused by aging filters. The sensor’s standard power and output specifications make it easy to retrofit to existing controllers.
