 Features Click here to view full-pdf specification sheets •Compact Assembly •Simple Installation •1/4 ” Threaded Con- nection •Detachable Signal Connector •PVDF Construction •Four Flow Ranges Application •Fluid Dispensing •Laboratory and Clinical Wet Benches •Chemical Dosing •Batch Processes Description The +GF+SIGNET 2507 Mini Flow Sensor contains a free-running rotor that is driven by the fluid flow.Within the given measurement range,the rotational speed of the rotor is proportional to the fluid flow rate.Permanent magnets built into the rotor actuate an electronic switch in the top of the sensor generating a square-wave output signal propor- tional to flow rate.Both opaque and transparent fluids can be measured from 0.2 to 20.0 centistokes.

Hand tighten only!Apply 1-2 turns of sealant to all threaded connections to prevent leaks. WARNI NG! Only hand tighten hand tighten hand tighten hand tighten hand tighten the fitting adapters to prevent over tightening while installing mating pipe connectors.Sensor damage will occur if the ports are over tightened. Installation Hints •Avoid vibrations and shocks •Avoid solids in the fluid •Install a filter or line strainer upstream to protect sensor Technical Data  Engineering Specifications •The sensor shall operate with a power input of 4.5 to 24 VDC @13 mA maximum. •The sensor shall provide an output signal via an open-collector transistor sinking a maximum of 10 mA. •Output shall be via a twisted pair,foil-shielded cable with drain wire. Supplied cable shall be at least 7.6 m (25 ft)long,with a maximum allowable length of 300 m (1000 ft). •Measurement repeatability shall be ±0.25%of full range. •The sensor shall be available in versions that accommodate nominal flow rates from: 0 to 2800 ml/min (0 to 0.749 gpm) 250 to 4250 ml/min (0.07 to 1 .12 gpm) 250 to 6000 ml/min (0.07 to 1 .589 gpm) 1500 to 12000 ml/min (0.4 to 3.2 gpm) •The sensor body and rotor shall be made of polyvinylidene fluoride (PVDF)that shall accommodate up to 80 psi @-30 °C (-22 °F)and 45 psi @120 °C (248 °F). •The sensor body shall be constructed to allow easy access for inspecting and cleaning internal mechanical parts without exposing electronic components. •The sensor shall provide 0.25 in.NPT male fittings for attachment to rigid pipe or tubing. •The flow sensor shall be +GF+SIGNET,Model 2507 Mini Flow.
