Page 3: Section 1 ! General Information
Rheotherm instruments are manufactured exclusively by Intek, Inc. and employ a patented thermal technique used by industry since 1978. The unique sensor designs have protected sensors, are easy to install and require little or no maintenance. -
Page 4: Description Of Operation
The rate at which heat is removed from the heated sensor by the stream is related to fluid velocity. 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. - 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: Section 2 ! Installation
SECTION 2 INSTALLATION 2.1 SENSOR !! WARNING: If the instrument has been selected for use in hazardous environments the model number shall end with the suffix -FM. The -FM notation designates that the instrument has been designed, manufactured for use, and reviewed by Factory Mutual (FM) as suitable for use in Class I, Division 1, Groups B, C, D, (Class I, Zone 1, IIB+H2 for US Only), Class II, Division 1, Groups E, F, G, Class III, Division 1, type NEMA 4X, T6 Ta=60... - Page 7 the line is via compression fittings, hose with clamp, threaded fittings or flanges, whichever is appropriate. Care must be taken not to transmit a twisting force through the sensor’s midsection. The TU and TUL sensors, whether flanged or not, must not be used to pull other piping together or to make up angular mismatch of fittings.

be avoided. Sudden pressure drops can cause the absorbed gas to release into the liquid, making the flow sporadic and difficult to measure. Control valves should be placed down stream of the sensor. The ideal installation will provide the sensor with well established smooth flow, uniform system temperature and consistent fluid media. -

Information Section). The instrument output will extend outside of the 4-20 mA range to signify an alarm condition. A low value will indicate a problem has been detected with the sensor. All other error types will produce an output value higher than 20 mA. The only expected time the signal will be outside the 4-20 mA level is for a few seconds after powering on the instrument. - Page 15 A quick reference guide is provided in the form of Table I which contains a list of available con- figuration options accessible using the display and the proximity sensors mentioned in SECTION 3.3 Local Display Configuration The Model 210 instrument with display option offers a user interface comprised of a 2x16 character LCD display, a status LED, and two proximity sensors.

Page 19: Section 4 ! Maintenance
SECTION 4 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 20 ‘Customer Mode’ when finished with diagnostics.)

Page 30: Palm Device General Information
SECTION 1 PALM DEVICE GENERAL INFORMATION The Rheotherm ® Model 210 flow instrument has the ability to communicate with a standard off-the- shelf palm device. This allows an operator to configure, calibrate, and access instrument status in a safe, quick, and easy manner. Using a palm device with custom Model 210 software, a wireless infrared (IR) link is established without the use of additional tools or hardware. - Page 31 !! !! WARNING: To perform a calibration adjustment for a "blind" instrument, the transmitter housing cover must be removed to access the IR communications port and a palm device is required. Since the instrument must be active to perform this operation, follow prudent safety procedures before attempting this procedure.

low and high values are at least 10% of full scale flow apart. E.g. if the full scale flow is 10 cc/min and your normal operating range is 6.5 - 7 cc/min then perform a low adjustment at 6 cc/min and a high adjustment at 7 cc/min. Restoring the Factory Calibration At any time the original factory calibration can be restored. - Page 35 Figure 6 - Display Configuration Form Change Display Navigate to the ‘Display Configuration’ option form.

A zero flow indication is possible when flow is above the calibration’s low limit. In this case, consecutive flow adjustments may be needed to stabilize the flow indication as the instrument adjusts itself away from the shutdown control limit.

6. REGISTER DEFINITIONS The Model 210 conserves memory space by not supporting coils or discrete inputs. This creates more space for holding and input registers where the process variables are stored. This modification does not affect the formation of a Modbus request packet, which will be demonstrated in the packet section. -
