Hence, the measured temperature differential between the reference sensor and heated sensor is a function of flow rate. Intek, Inc. is licensed to use this patented and trademarked flow measurement method. - 3 -... -
Page 4: Precautions
The Rheotherm Flow Controller is an addition to a standard Rheotherm Flow Meter. It uses a calibrated flow rate measurement to control an adjustable valve to the desired setpoint. The valve and sensor calibration will be sized to your specific application, with the desired set point, if specified, near the center of the calibration range. - Page 5 Any special information pertaining to your unit is covered under CUSTOM INFORMATION (SECTION 6). Time should be taken to carefully read these instructions prior to installation of the equipment. Should any questions arise or problems occur, call Intek for immediate assistance.

Page 6: Installation
INSTALLATION 2.1 SENSOR !! CAUTION: All sensors have a directional arrow on the tag and/or etched into a metal part. All flow controllers are assembled with the valve on the downstream side. 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. -
Page 7: Transmitter Electronics
you are using a pump of this type, it is recommended that a pulsation dampening device be used to provide smooth continuous flow. For liquid measurement systems using high pressure gas to force flow, the effects of the absorbed gas must be considered. In these cases, sudden pressure drops up stream of the sensor such as line size expansions, control valves, and pressure dropping regulators must be avoided. -
Page 8: Electrical Connections
2.3 ELECTRICAL CONNECTIONS 1. Verify/configure the input power. The input power requirement is listed on the tag on the transmitter enclosure. Be sure the input power source to be used is properly selected in the unit. Unless specifically ordered otherwise, the input power requirements are 24±2Vdc @ 0.25A typical. -
Page 9: Operation
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). -

3. Setpoint Adjust — Instruments with an FCP in the serial number are controlled by an onboard potentiometer. To adjust this potentiometer, unscrew the enclosure window and use a small tweaker or screwdriver to turn the dial up or down. Instruments with an FCE in the serial number use a 0-5v analog input to control the setpoint. -
Page 11: Maintenance
MAINTENANCE 4.1 GENERAL MAINTENANCE Certain precautions should be taken to ensure proper performance of all models of flow instruments. Since the measurement technique involves a signal resulting from heat transfer to the flowing medium, care should be exercised to prevent build-up of varying layers on the walls of the sensor. Layers such as bacterial growth, dried paints, gas bubbles and non-solubles can result in measurement below actual flow rates. - Page 12 4-20 mA output will be set either below 4 mA or above 20 mA depending on the type of problem found. The following tables provide easy-to-follow instructions to troubleshoot flow indication problems and interpret instrument fault codes. TABLE I.

5.3 FACTORY AND FIELD SERVICE If you request field service, Intek has experienced engineers available to meet your needs. Many of the repairs or recalibrations will require returning the instrument to the factory. If a problem cannot be solved over the phone, with your help, we will determine if factory service or field service will be the best solution. -
