Introduction This manual is a service guide produced by the manufacturer. The manual provides specific procedures and/or illustrations for installa- tion, inspection, cleaning and filtration of all Omega FPR 200 flow sensors. When properly followed, these procedures will keep your flow sensor operating dependably for many years. It is important for operators and maintenance personnel to be safety conscience when operating or repairing equipment. Developing a thor- ough knowledge of the precautio

Illustration 1: Mounting Instructions Installation - Mechanical 1. The flow sensor has NPT (National Pipe Thread) plumbing con- nections. It is recommended that a paste type pipe sealant be used on these threads. [Teflon tape sealant can be used as long as it is applied in such a way that it will not enter the flow stream. Pieces of Teflon tape can wrap around the turbine and impede its rotation.] 2. The recommended mounting orientation would be any plane that will place the axis of the tur

4. It is recommended that the sensor be placed in such a position that the round access cover can be removed for cleaning and tur- bine servicing. It is also recommended that a union be placed near the sensor to allow easy removal. Note1: The flow sensor is a bi-directional measuring device. References to “inlet” and “outlet” refer to uni-directional systems. Installation - Electronic (4-20mA Only) The flow sensor circuit is a two-wire loop-powered design that transmits a 4-20mA signal that i

Apply the DC supply voltage directly across the sensor wires. If the LED does illuminate, the load is either: too great of imped- ance or an open circuit. If the LED does not illuminate, the sen- sor's lead wires or circuit are defective. 6. The installation should be complete. Installation - Electronic (0-5VDC Output Only) 1. Connect the red wire (pin 1 for units with the electronic disconnect option) from the sensor to the positive terminal of the 12-35 VDC power supply. 2. Connect the bl

Installation - Electronic (Pulse Output Only) The flow sensor pulse output circuit is a three-wire DC-powered design that transmits a frequency proportional to flow rate. The circuit operates on 5-24 VDC and will consume a maximum of 25 mA from the power supply. 1. Connect the red wire (pin 1 for units with the electronic disconnect option) from the sensor to the positive terminal of the 5-24VDC power supply. 2. Connect the black wire from the transmitter (pin 2 for units with the electronic

Installation - Electronic (Relay Output Only) 1. Connect the red wire from the sensor to the positive terminal of the 12-35 VDC power supply. 2. Connect the black wire from the transmitter to the negative terminal of the 12-35 VDC power supply. 3. (Versions with stainless steel sensor body only) Be sure to properly ground the flow sensor by using the ground screw shown in Illustration 2 to GROUND SCREW connect the sensor body Earth ground. This step may be unnecessary if the piping system t

Set Point Adjustment (Relay Output Only) 1) Adjust the flow rate through the line in which the flow sensor is installed to the rate that corresponds to the desired relay trip point. 2) If the red LED on the back side of the sensor is not illuminated, use a small flat bladed screwdriver to slowly turn the adjustment screw on the set point potentiometer counter-clockwise until the red LED illuminates. 3) If the red LED is already illuminated, turn the adjustment screw on the potentiometer clock

1. Relieve pressure in the piping system. 2. Remove the retainer ring that secures the turbine access cover. 3. Remove the access cover with a pliers, taking care not to damage the o-ring seal. 4. Pull out the turbine assembly and the shaft. 5. Inspect the shaft for things that may have wrapped around it. 6. Inspect the turbine bearing surface for wear and elongation. Replace as necessary. 7. Clean any rust off of the magnets that may have accumulated. 8. Reassemble the unit by placing the tur
