GENERAL INFORMATION The complete lack of moving parts of this insertion flow sensor is the source of its reliability. There is no rotor to stop turning in dirty water and there are no bearings to wear out. Brass, stainless, and PVC models withstand a variety of temperature, pressure, and chemical conditions. Reverse flow output and submersibility are optional. SPECIFICATIONS Power 12 – 24 Vdc, 250 mA max Flow RaNGE 0.2 – 20 ft/sec FITTING SIZE EX101/201B/S: 1.

INSTALLATION Piping. For best results, the EX sensor should be installed with at least ten diameters of straight pipe upstream and five downstream. Certain extreme situations such as partially-opened valves are particularly difficult and may require more straight diameters upstream.

INSTALLATION EX101/201 INSTALLATION Fitting Installation. EX101/201 sensors come with a male NPT pipe thread adapter fitting (brass and stainless: 1 1/2”; PVC: 2”). Any fitting that provides the matching NPT female thread may be used. Installation procedure compensates for fitting height differences. Cut a minimum 1-3/4” hole in the pipe. If possible, measure the wall thickness and write it down for use in depth setting. Then install the threaded fitting (saddle, weldolet, etc.) on the pipe.
PAGE 6
INSTALLATION Depth Setting. It is important for accuracy that the sensor be inserted the correct depth into the pipe. Follow these steps: PROPER DEPTH SETTING 1. In Table 1, find Dimension C for your sensor model, material and pipe size. "D" 2. Subtract wall thickness of your pipe to find Dimension D. Use Table 2 if you do not know the thickness.

ELECTRICAL CONNECTIONS General Electrical Guidelines: Reverse Flow Output: Reverse flow output is available as an option. This open-collector isolated output does not supply power. It functions like a polarity-sensitive switch closure. Note: This output is limited to 6 mA at 30 Vdc maximum. • Whenever possible avoid running control cables in the same conduit with AC power. • Using shielded cable, be sure that one end is grounded.

OPERATION & MAINTENANCE Zero Adjustment. When the EX100/200 Series meter is powered up and there is no flow, there should be no output pulses (or, if connected to the FT420, flow rate should read “0”). If there are pulses it may be necessary to adjust the flow meter under no-flow conditions after it has been installed. This should only be done if the indicated flow is low, near the lower cutoff. Calibration (“K-Factor”).
