    Do not install the product outdoors without additional weather protection. Caution: In order for the ILVA20 flowmeter to meet its specified accuracy and performance, it is essential that the following guidelines for installation are followed carefully. For steam flow measurement, good basic steam engineering practices should be followed as detailed in this manual.
  • Page 14 Required installation Isolation valve minimum minimum Strainer Separator Fig. 4a Minimum 100 mm Minimum 100 mm Fig. 4b The MVT10 is supplied with a four bolt bracket and two U bolt fixings for mounting to a suitable structure. The U bolts can be used to clamp the MVT10 to a suitably located pipe or bar up to 60 mm diameter, see Figure 4a. Caution! Do not clamp the MVT to another steam pipe.
  • Page 15 4.1 Orientation The ILVA20 should be installed in a horizontal line. As it has been calibrated in a horizontal attitude, mounting it in a vertical line (flow downwards) may introduce a small flow measurement error. If installation with flow vertically downwards is unavoidable, please consult Spirax Sarco for advice.
  • Page 16 Maximum 45º Fig. 9 The ILVA20 can be rotated in a horizontal line by up to 45° (downwards only), see Figure 9. The filling and hose connector plugs are supplied loose and thus need to be fitted to suit the orientation of the 2 way manifold.
  • Page 17 The ILVA20 normally only requires a minimum of 6 pipe diameters upstream and 3 downstream of clear straight pipe. These dimensions assume a measurement from a single 90° bend.
  • Page 18 If any of the following configurations are present upstream of the ILVA20, then it is recommended that the minimum upstream clear pipework is doubled to 12 diameters. Two right angled bends in two planes. Pressure reducing valve. Partly open valve.
  • Page 19 Fig. 14 It is important that the ILVA20 is located centrally in the pipework as any eccentricity may cause inaccurate readings. The ILVA20 has been designed with integral centering webs which locate on the internal diameter of the pipework.
  • Page 20 4.4 Pressure tappings The ILVA20 has a two way manifold with integral pressure tappings for connection to the MVT10 mass flow transmitter assembly using impulse lines. These are threaded 3/8" NPT and are clearly marked HI (upstream) and LO (downstream). Care should be taken to ensure that these are correctly connected. It also has filling points to commission the assembly.
  • Page 21 4.5 Hard piped impulse lines The ILVA20 and MVT10 can be installed with hard piping for impulse lines (supplied by others). The general arrangement Fig. 16 should be as shown opposite. Hard piping for impulse lines 4.6 How to fit the MVT10 MVT10 is supplied with a bracket which can be clamped to small pipe (Æ60 mm), or fixed to a suitable wall.
