    Chapter 1: Introduction InnovaMass. Reinvented. In the 1990s, Sierra designed and introduced InnovaMass, the first multivariable mass vortex flow meter in the world. Through a single process connection, InnovaMass now empowered customers with mass flow rate, volumetric flow rate, density, temperature and pressure.

  • Page 12 Both the inline and insertion configurations are similar in that they both use identical electronics and have similar sensor heads. Besides installation differences, the main difference between an inline flow meter and an insertion flow meter is their method of measurement. For an inline vortex flow meter, the shedder bar is located across the entire diameter of the flow body.

  • Page 13: Chapter 2: Installation Installation Overview

    Chapter 2: Installation Installation Overview Sierra’s InnovaMass Vortex Flow Meter installations are simple and straightforward. Both the 240i Inline and 241i Insertion type flow meter installations are covered in this chapter. After reviewing the installation requirements given below, see page 14 for 240i installation instructions.

When using toxic or corrosive gases, purge the line with inert gas for a minimum of four hours at full gas flow before installing the flow meter Cold Tap Guidelines Refer to a standard code for all pipe tapping operations.
  • Page 18 Hot Tap Guidelines Hot tapping must be performed by a trained professional. U.S. regulations often require a hot tap permit. The manufacturer of the hot tap equipment and/or the contractor performing the hot tap is responsible for providing proof of such a permit. All flow meter connections, isolation valves, and fittings for hot tapping must have the same or higher pressure and temperature rating as the main pipeline.
  • Page 19 Connect isolation valve and test for leaks xxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxx Purge pipe xxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxx Figure 4. Hot Tap Sequence Flow Meter Insertion The sensor head must be properly positioned in the pipe. For this reason, it is important that insertion length calculations are carefully followed. A sensor probe inserted at the wrong depth in the pipe will result in inaccurate readings.
  • Page 20 Installing Flow Meters with a Compression Connection Use the following formula to determine insertion length for flow meters (NPT and flanged) with a compression process connection. The installation procedure is given on the next page. Figure 5. Insertion Calculation (Compression Type) Example: To install a 241i meter with a standard probe (S = 32.0 inches) into a 14-inch schedule 40 pipe, the following measurements are taken:...
  • Page 21 Insertion Procedure for Meters with a Compression Connection Figure 6. Insertion Flow Meter with Compression Type Fitting The sensor alignment pointer must point downstream, in the direction of flow. To avoid serious injury, DO NOT loosen the compression fitting under pressure.
  • Page 22 5. Align the sensor head using the sensor alignment pointer. Adjust the alignment pointer parallel to the pipe and pointing downstream. 6. Tighten the compression fitting to lock the stem in position. When the compression fitting is tightened, the position is permanent. Installation of Meters with Packing Gland Connection Use the following formula to determine insertion depth for meters with a packing gland connection (NPT and flanged)
