The goal of Calibration Validation is to provide operators with the ability to verify that the meter is capturing accurate data at scheduled recalibration times - or at any time - instead of sending the meter back to the factory for recalibration.
  • Page 20 Introduction Flow Calibration Every TM100 flow meter is set to the customer's configuration at the factory using an App ID which is generated by the on-line configurator. The App ID specifies the gas type, flow range, serial communication and other settings in the meter. If these settings match the final customer application, the meter is ready to use.

    TM100 Installation Installation Scope This section describes how to install the Sierra Instruments TM100 Flow Meter and how to get started. Installation methods will vary according to the flow meter type (insertion or inline). For TM100 Insertion Types: Determine lateral position on the pipe.

  • Page 23: Lateral Placement

    Instructions for Flow Meter Lateral Placement Install the TM100 flow meter so that it is far enough away from bends in the pipe, obstructions, or changes in line sizes to ensure a consistent flow profile. See Fig. 2.1 below for your meter type.
  • Page 24 Fig. 2.2:  Installation at 180° Alternate Installations - Vertical Pipes or Restricted Installation Spaces When restricted physical installation space exists, the TM100 can also be installed at other angles. Please note that the display and the enclosure orientation can be rotated in 90° increments.
  • Page 25 2. Assemble the compression fitting and branch fitting hand tight onto the probe of the TM100. 3. Insert the probe into the hole in the pipe and use the TM100 probe and compression fitting to align the branch fitting with the hole and the probe perpendicular to the pipe.

  • Page 26: Installation Depth

    TM100 Installation Installation Depth The installation depth of the sensor in the pipe is dependent on the pipe size. To get the most accurate reading, proper placement of the sensor window within the pipe is necessary. As shown in Fig 2.5, the end of the sensor window should be 0.73" (18.5 mm) past the center line of the pipe.

  • Page 27: Mounting Instructions

    Installation Mounting Instructions - Compression Fittings (TM100 Only) The TM100 is mounted through a 0.781" hole and a female NPT branch outlet in the customer's pipe. Insertion style flow meters are not designed for use in pipes smaller than 1½".
  • Page 28 TM100 Installation Mounting Instructions - Compression Fittings (Inline and Insertion Meters Previously Installed) In cases where a compression fitting has already been swaged in an inline flow body or an insertion meter, use the following procedure. • Carefully insert the probe with swaged ferrules into the fitting until the front ferrule seats against the fitting (see Figure 2.7).
  • Page 29 Installation Rotating the Enclosure The TM100 enclosure has been designed to allow the enclosure to rotate for optimal viewing of the display. To rotate the enclosure, first loosen the two set screws near the Flow Direction Indicator, then unscrew and remove the flow direction indicator. Rotate the enclosure into the desired position, reinstall the flow direction indicator, and tighten the set screws.
  • Page 30 TM100 Installation Changing the Orientation of the TM100 Optional Display The optional display can be rotated in 90° increments for optimum viewing of the screen. First, open the enclosure by unscrewing the enclosure cap and loosen the two captive screws to open the display assembly.
  • Page 31 TM100 Installation Installation of a New Retractor Assembly 1. Remove collar clamp from probe using a 3/16" Hex Key. 2. Remove meter probe from retractor assembly and leave the ball valve open. Keep the collar spacer on the probe so it is not misplaced.
  • Page 32 TM100 Installation 4. Carefully slide the probe through the retractor assembly and through the hole to see if there is interference by touching the pipe wall with the end of the probe on the far side or until the probe cannot go deeper.
  • Page 33 TM100 Installation 5. Using the equation (L + D/2 + 0.73") from Figure 2.12, calculate the insertion depth and mark on the probe while measuring from the end of the probe. 6. The Retractor Clearance table of Figure 2.21 lists the space required to remove the meter from the retractor.
  • Page 34 TM100 Installation 7. Insert probe back into the retractor to the depth mark and hand-tighten the compression fitting. Make sure collar spacer is in place on the probe. 8. Verify that flow direction indicator is in line with pipe and in the direction of flow.

If the voltage supplied at the input terminals of the TM100 is not within the range of 10VDC to 30VDC, a variety of problems can occur including a dim display, inaccurate flow readings or faulty 4-20mA, pulse and communication interface.

  • Page 98 TM100 Troubleshooting Alarm Codes continued The VTEMP Voltage is out of the acceptable range. This may be a result of failed electronics, VTEMP Volt Error parameters, or sensor connections. Refer to action of Alarm Code 22. The Delta T error between the sensor elements is too large. This may be a result of failed Delta T Error electronics, parameters, or sensor connections.
