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.
Installation - Mec hanical 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. [T eflon tape sealant can be used as long as it is applied in such a way that it will not enter the flow stream.
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.
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 (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 V DC and will consume a maximum of 25 mA from the power supply .
Installation - Electronic (R elay Output Onl y) 1. Connect the red wire from the sensor to the positive terminal of the 12-35 V DC power supply . 2. Connect the black wire from the transmitter to the negative terminal of the 12-35 V DC power supply . 3.
Set P oint 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.
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.
