Rotorflow INTRODUCTION RotorFlow(R) Sensors Provide Visual Indication, Continuous Sensing and Accurate Switching Bright, visual indication with choice of pulsed DC output, or adjustable 1 amp switched output Flow ranges from .1 GPM to 60.0 GPM RotorFlow Series Sensors are U.L. Recognized -- File No. E45168. Compact inline housings Available in high performance plastic, brass, or stainless steel housings 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(R) Series. GEMS new generation of RotorFlow(R) 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. High Resolution or High Visibility Rotors. 7/16 Hex Hub Ceramic Shaft Heavy Duty, Buna N O-Rings Brass, Stainless Steel or High Performance, Polypropylene Bodies FLOW SENSORS - ELECTRONIC 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. Now for line sizes up to 1! 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. New wide-body senses flow up to 60 GPM. 3/4 and 1 line models. Visit www.GemsSensors.com for most current information.

RFO TYPE Pressure Drop-Typical HALL EFFECT SENSOR SENDS A VOLTAGE PULSE WITH EACH PASS OF MAGNETIC FIELD Standard Flow Range Units 12 9 0 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.

F-7 Easy Installation and Maintenance Panel Mounting 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. 8 MIN 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) (20 CM) 8 MIN (20 CM) 2.50 (63.5 mm) Incoming Flow Incoming Flow Low Flow Adapter Low Flow Adapter FLOW SENSORS - ELECTRONIC 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(R)" or 2 wraps of Teflon(R) 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.

M12 x 1 (4-Pin) (1 meter cable included) CE Calorimetric Principle/Thermal Dispersion The operating principle of the FS-600 flow switch is based on the calorimetric principle. The FS-600 uses the cooling effect of a flowing fluid or gas to monitor the flow rate. The amount of thermal energy that is removed from the tip determines the local flow rate. This temperature-based operating principle can reliably sense the flow of virtually any liquid or gas. The sensor tip of the FS-600 flow sensor houses two transistors and a heater element. One transistor is located in the sensor tip, closest to the flowing fluid. This transistor is used to detect changes in the flow velocity of the liquid. The second transistor is bonded to the cylindrical wall and is a reference for ambient fluid conditions. In order to make the sensor sense flow, it is necessary to heat one of the transistors in the probe. When power is applied, the tip of the probe is heated. As the fluid starts to flow, heat will be carried away from the sensor tip. Cooling of the first transistor is a function of how fast heat is conducted away by the flowing liquid. The difference in temperature between the two transistors provides a measurement of fluid velocity past the sensor probe. When fluid velocity is high, the temperature differential is small. As fluid velocity decreases, there is an increase in temperature differential.
