Description The Signet 2507 Mini Flow Sensor contains a free-running rotor which is driven by the fl uid fl ow. Within the given measurement range, the rotational speed of the rotor is proportional to the fl uid fl ow rate. Permanent magnets built into the rotor actuate an electronic switch in the top of the sensor generating a square- wave output signal proportional to fl ow rate. Both opaque and transparent fl uids can be measured from 0.2 to 20.0 centistokes. Wetted sensor parts are constructed of PVDF and FPM, making the sensor suitable for use with most process fl uids, including most acids, bases, light oils, and solvents.

2 3. Installation • The sensor may be installed in any position,although horizontal fl ow is recommended (the sensor mounted upright). If the sensor is not installed upright, the linearity error may be greater in the lower part of the sensor's measurement range. • Mounting tabs are provided using M4 or #8 self-tapping screws (customer supplied). See Dimensions illustration for mounting tab hole pattern specifi cations. • Install sensor with the arrow pointing in the direction of fl ow. • Always maximize distance between the sensor and pump source. Never install immediately downstream of valves, fi ttings, etc. For optimum performance, a straight fl ow run of at least 100 mm to 150 mm (4 to 6 in.) should be provided before and after the sensor. • Two pipe fi tting adapters (included) convert the G 1/4 in. straight threads to 1/4 in. NPT pipe threads. Hand tighten only! Apply 1-2 turns of PTFE sealing tape to all threaded connections to prevent leaks.. Installation Hints • Avoid vibrations and shocks. • Avoid solids in the fl uid. • Install a fi lter or line strainer upstream to protect sensor. 1 2 Sensor Ground (silver wire) Sensor Power: 5 to 24 VDC (black wire) Sensor Signal Output (Red wire) Max cable length: 300 m (1000 ft) Sensor Plug (side) Disregard ground symbol on connector 95 mm 65 mm FLOW FLOW 68 mm 4.

Do not use tools of any kind on the sensor body or port connections. Hand tighten only! Excessive force will damage sensor. 6. Replacing The Flow Insert Sensor range can be modifi ed by changing the fl ow insert. The sensor must be removed from service and disassembled prior to installing the new fl ow insert. See Specifi cations (Section 2) for fl ow range data. Flow Insert Replacement Procedure: 1. Depressurize system and remove sensor. 2. Rotate the upper sensor body clockwise until it releases from the lower half, then lift off. 3. Remove rotor and quad ring seal from lower body. 4. Push the fl ow insert outward using a small screwdriver. 5. Install the new fl ow insert (small diameter inward) with the eraser end of a pencil. Apply light pressure until insert seats against the step in the lower body. Do not force! 6. Install rotor into lower body. Spin rotor with fi nger and check for free rotation. If rotor hits fl ow insert, remove rotor and push insert back until free rotor rotation is established. Use a rounded object like a pen or pencil body to adjust fl ow insert depth. 7. Install rotor, quad ring, and upper body. Hand tighten only! Do not overtighten upper body or the lower body assembly tabs will break. 8. Reprogram instrument with new K-Factor, see Calibration (Section 5). IMPORTANT! • K-Factors must be considered as approximate values. • The number of pulses per volumetric unit may vary depending on the medium and the installation. • For optimum performance, the system must be calibrated after installation.
