4. WARNING The sensors no user serviceable parts so do not try to disassemble Permanent damage may result CAUTION sensors have a directional arrow on the tag and or etched into a metal part Before installing a sensor please note proper flow direction This is critical to instrument performance The sensor style supplied with your meter is listed in the model code number in SECTION 6 Proper installation of the sensor is necessary for achieving accuracy and repeatability Installation suggestions for each type of standard sensor are given here and instrument detail drawings may be included in the appendix For custom sensor installations refer to CUSTOM INFORMATION SECTION 6 Be sure wetted surfaces are clean before installing If cleaning is needed use non residue solvent and wipe dry Some sensor terminations are enclosed in an aluminum housing and if it is not sealed properly can easily be damaged by moisture and corrosion Make sure the lid is tightly sealed and the gasket if supplied is in place 1 TU or TUL nonintrusive capillary 16 and TU TUL sensors particularly require special care in handling and installing to avoid damage to sensor tube and tube stubs 11 WARNING TU and TUL sensors are made with thin walled tubing use care when installing All TU TUL sensors larger than inch should have straight line input and output sections typically 20 pipe diameters on the in

SECTION 3 OPERATION 3 1 START UP Typically the instruments have been configured by the factory for the flow range of interest specified by the customer After installation has been completed all that is required is to switch on power and initiate flow in the measurable flow rate range Flow sensors that are not calibrated directly on the fluid to be measured are so indicated in this manual SECTION 6 In this case an in line field calibration is required When power is first turned on the 4 20 mA output will be low alarm condition while booting followed by the output starting near 100 During startup of units with a display the alphanumeric display will show INTEK onthe top line and 614 895 0301 the bottom display line After fifteen to sixty seconds depending on flow meter response the reading will stabilize 3 2 GENERAL INFORMATION The Rheotherm instrument is compensated for a wide range of both ambient and flowing media temperatures However abrupt changes in the temperature of the flow stream can cause the instrument output to deviate from the true representation of flow rate An accurate reading is obtained only when the sensor is in thermal equilibrium with the flowing liquid or gas Typically a 10 C abrupt change in temperature may require 40 seconds to stabilize To maintain optimum accuracy temperature ramps should be kept below 1 C minute Rheotherm instruments are calibrated for a particular fluid eit
