The paddle or vane moves against a spring mechanism in the direction of flow with respect to the amount of flow in the pipe. A magnet is located on the end of the vane inside the lower housing. A second magnet located inside the upper housing moves from magnetic attraction with the magnet attached to the vane. This upper magnet is attached to a lever arm that activates a snap switch. The upper housing and lower housing are separated by solid metal with no linkages or mechanisms to fail or wear creating leaks. The spring mechanism returns the vane to the original position as flow decreases.ExampleSeries Construction Lower Body Circuit Type Connection SizeVane Size Tee & Tee Material Options V7V7W W B B S S S 3300N N ST ST RV V7-WBS-30N-ST V7 Flow Switch Weatherproof Brass 316 SS SPDT1˝Full length vanewith templateNo Tee SS tagReinforced vaneINSTALLATIONUnpackingRemove the V7 from the shipping carton and remove any packaging material.Inspect for damage.

Use the ToughNet switch as a guide to mark the correct positions of the 4 screws.STEP 2: Use the 4 screws in thepanel mounting kit. If you wouldlike to use your own screws, makesure the screw head is between6.0 mm and7.0 mm in diameterand the shaft is less than 4.0 mmin diameter, as shown at the right.Do not screw the screws in all the way—leave a space of about 2 mm to allow room for sliding the ToughNet switch between the wall and the screws. NOTE Before tightening the screws into the wall, make sure the screw head and shaft size are suitable by inserting the screw through one of the keyhole-shaped apertures of the ToughNet switch.STEP 3: Once the screws are fixed in the wall, hang the ToughNet switch on the 4 screws through the large opening of the keyhole-shaped apertures, and then slide the switch downwards. Tighten the four screws for added stability.NOTE To provide greater protection from vibration and shock, use screws with shaft diameter between 6.0 mm and 7.0 mm, and fix the ToughNet switch onto the wall directly through the large opening of the keyhole-shaped apertures.Wiring RequirementsPlease read and follow these guidelines:•Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the intersection point.NOTE: Do not run signal or communications wiring and powerwiring through the same wire conduit. To avoid interference, wires with different signal characteristics should be routed separately. •You can use the type of signal transmitted through a wire to determine which wires should be kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can bebundled together.•Keep input wiring and output wiring separated.•It is strongly advised that you label wiring for all devices in the system when necessary.Grounding the ToughNet SwitchGrounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the grounding screw to the grounding surface prior to connecting devices.Connecting the Power SuppliesThe ToughNet TN-G6512 Series switches support dual power inputs—power input 1 and power input 2. The M12 K-coded 5-pin maleconnector on the TN-G6512 Series switches' front panel is used for the dual power inputs.

Switch ratings are suitable for many solid state control systems and monitors or alarms. Simple relay interfaces can be used for higher current applications. Two basic styles offer a choice of vertical or hori-zontal mounting. Hermetically sealed reed switches are actu-ated by magnets permanently bonded inside the float and can be easily adapted to open or close a circuit on rising or falling levels.SWITCH ACTION (Normally open/Normally closed)Vertical ModelsVertical mount models are shipped with normally open switch contacts which close as the float rises toward the mounting threads. Reverse switch action by removing the float, rotating it end-for-end and replacing it on the stem.Horizontal ModelsHorizontal models are in the normally open position when the indicating arrow points up (float is down), and normally closed when the arrow points down (float is up).INSTALLATIONChoose a location away from fill pipes, drains, or other areas where turbulence or wave motion might occur. Turbulence will cause false actuation and shorten contact life. Excess conta-minants in fluid may inhibit float operation and occasional wipe-down may be necessary. Care should be taken that switches are always operated within electrical ratings. Read and understand all safety precautions on back of this sheet before installing.MOUNTINGInstall vertical mount models in an appropriate 1/8″NPT fitting.Vertical models mount internally, oriented within 30°of vertical,or select optional fittings for external mounting. Models F7-HPS-1 and F7-MHS must be mounted internally, which means the switch must be secured to the wall of the tank or vessel from the inside. Install horizontal model F7-HPS-1 in a 5/8″(16mm) hole or model F7-MHS in a 1/2″(12.7 mm) hole. Secure into place with the nut provided. Tank wall should not exceed 1/8″(3 mm). Model F7-HPS-2 requires a horizontal 1/2″NPT female fitting and can be fitted to the tank or vessel from the outside. Model F7-HSS requires a horizontal 1/2″NPT female fitting and can be mounted from the inside or outside (inter-nally or externally) of the tank or vessel.DIMENSIONS, INCHES (MM) - Vertical MountModel (A) Stem (B) Float (C) Float (D) Actuation Number Length Diameter Height from HEX*F7-SB 2.75 (70) 1.13 (29) 1.38 (35) 1.2 (31)F7-SS2 2.06 (52) 1.0 (25) 1.0 (25)0.73 (19)F7-PP 2.18 (55) 1.18 (30) 1.0 (25)0.69 (18)F7-BT2.18 (55)1.18 (30)1.0 (25)0.69 (18)PHYSICAL DATAModel Material Max.Max.Min.Approx.Number Float/Stem Temp.Press.S.G.Deadband Vertical Mount F7-SB Buna-N & Epoxy/220°F 150 psig 0.601/16″316SS105°C 10 bar 2 mm F7-SS2316/SS (CYC)/300°F 450 psig 0.751/16″316SS149°C 31 bar 2 mm F7-PP Polypropylene & Epoxy/220°F 100 psig 0.601/8″Polypropylene105°C 6.89 bar 4 mm F7-BT Buna-N & Epoxy/220°F 150 psig 0.451/8″PBT*105°F 10 bar4 mm Horizontal Mount F7-HPS Polysulfone/185°F 150 psig 0.853/16″-1, -2Polysulfone 85°C 10 bar5 mm F7-HSS 316SS/316SS 392°F 300 psig 0.601/8″200°C 20.7 bar4 mm F7-MHS316 SS/316SS392°F 100 psig 0.703/16″200°C6.89 bar5 mm*DistancebetweenHEXandliquid(S.G.=1)******************************specific gravity changes.* PBT - Polybutylene Terephtalate3.750[95.3]1/2-13 THREAD2.875 [73]1.00[25.4]1.00 NOM.[25.4]1.375[34.9].1875 [4.76]F7-MHS, INTERNAL HORIZONTAL MOUNTDWYER INSTRUMENTS, INC.

Wall thick-ness should not exceed 1/8″(3mm).When preparing wires for termination, avoid pulling against the resin seal or end plug of the float switch. Units with tapered pipe threads should be treated with Teflon®based thread compound or tape before insertion in fitting.Sufficient torque is achieved at hand-tight plus one half turn.CIRCUIT INFORMATION FOR REED SWITCH PROTECTIONREAD INFORMATION BELOW BEFORE INSTALLING YOUR NEW REED SWITCH CONTROL!Exceeding the current capacity of this Reed Switch control may cause FAULTY OPERATION! Be aware of the inductive and capaci-tive or lamp loads you may be placing on your Reed Switch Control. the circuits below outline possible solution to preventing over-loads due to inrush or surge currents exceeding maximum or when the switch current and product of the inductive back EMFexceed the switch’s power rating. Also, the circuit for prevention of overload when switching filament lamps (low “cold” resistance) is outlined below. Failure to follow these measures to protect Reed Switch Contacts may cause the contacts to weld together or result in premature wear.Possible Circuit Solutions Indicated by Dashed LinesInductive Loads Possible causes-An electromagnetic relay, electro-magnetic solenoid, electromagnetic counter with inductive component as circuit load.Capacitive Loads Possible causes-A capacitor connected in series or parallel with Reed Switch Control. In a closed circuit, a cable length(usually greater than 50m [162.5 ft])used to connect reed switch may also introduce static capacitance.Lamp Loads Possible causes-A tungsten filament lamp load.。

红色LED亮: 断流或流速 低于设定值 开关释放 或模拟量处 于4mA
黄色LED亮: 流速等于设 定值开关动 作
将流量开关装好，使介质以需要监测的流速流动，调整电位计, 使第一个绿色LED恰好变亮。此后当流速低于当前值时，开关 就释放。 若要使开关点比当前流速小，可调整电位计使绿色 LED多亮一些。
将流量传感器装好，使使介质以需要监测的上限流速流动，调整旋钮，使 第五个绿色LED亮（20mA）；此后，输出将正比于静止和上限之间的流 速，即 4mA对应静止流速，20mA对应上限流速.
