 Description Constructing a flow monitoring or controlling system is simple with the +GF+ SIGNET 2536 Low Flow Sensor. Combine the 2536 with a +GF+ SIGNET installation fitting and flow meter or controller, and have an operational flow monitoring system in minutes. Available in a choice of chemically resistant housing materials, the 2536 stands up to many industrial processes. For processes containing pure water or acids and solvents, the PVDF version combined with a PVDF +GF+ SIGNET fitting, provides protection from possible fluid product contamination.

Technical Data a)1/2 in.NPT Conduit Connection b)Large bail simplifies insertion/removal c)High-strength ring nut with provision for lead seal installation d)Dual O-ring seal (Viton ® standard,EPR optional) e)Molded one-piece black glass-filled Polypropylene or natural PVDF body f)Multiple pin materials g)Open-cell rotor with material options See pdf sheet for more details Installation For maximum linearity and accuracy, the sensor should be located in a straight run of pipe upstream and downstream of the sensor. Major obstructions such as pumps or throttled valves will require longer straight runs. Engineering Specifications for both 515 and 2536 Flow Sensors •The flow sensor shall use a four-blade,open-cell rotor design using insertion paddlewheel technology. •Linearity of the output signal with respect to flow rate shall be ±1 %of full range. •Measurement repeatability of the output signal with respect to flow rate shall be ±0.5 %of full range. •The sensor body shall be made of injection-molded polypropylene (PP)that shall accommodate up to 12.5 bar @20 °C (180 psi @ 68 °F)and 1.7 bar @90 °C (25 psi @194 °F).As an alternative,the sensor shall be made of injection-molded polyvinylidene fluoride (PVDF)that shall accommodate up to 14 bar @20 °C (200 psi @68 °F)and 1.7 bar @100 °C (25 psi @212 °F). •The sensor shall attach to a pipe via a variety of insertion-style installation fittings supplied by the flow sensor manufacturer. Attachment shall use a 1-1/4 X 11-1/2 NPSM threaded cap.Sealing shall be accomplished with a double O-ring seal.O-rings shall be made of FPM-Viton,FPM-Kalrez or EPDM. •The sensor shall be equipped with 0.5 in.female conduit connection. Engineering Specifications for +GF+SIGNET 515 Rotor-X Flow Sensor •The sensor shall require no electrical power. •The sensor shall provide an output signal of 3.3 V p-p per m/s nominal (1 V p-p per ft/s)at a frequency of 19.7 Hz per m/s nominal (6 Hz per ft/s)from 0.3 to 6 m/s (1 to 20 ft/s). •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 60 m (200 ft). •The operating range of the sensor shall accommodate nominal flow rates from 0.3 to 6 m/s (1 to 20 ft/s). •The sensor shall meet appropriate CE standards and FM standards for Classes 1,11 and 111,Division I/Groups A-G. Engineering Specifications for +GF+SIGNET 2536 Low Flow Sensor •The sensor shall operate with a power input of 3.3 to 6VDC @<1.5 mA or from 6 to 24 VDC @<20 mA. •The sensor output shall provide an open-collector pulse at a frequency of 49.2 Hz per m/s nominal (15 Hz per ft/s). •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). •The operating range of the sensor shall accommodate nominal flow rates from 0.1 to 6 m/s (0.3 to 20 ft/s). •The sensor shall meet appropriate CE standards.
