Installation Overview
Side-Trak™and Auto-Trak™transducers are supplied with either compression, VCO, VCR or NPT process connections. To ensure a successful installation, inlet and outlet tubing should be in a clean state prior to plumbing the transducer into the system. The ship- ping caps covering the inlet/outlet fittings should not be removed until immediately prior to installation.
Before installing the transducer, verify the following:
1.Make sure the installation site meets the specific operating pa- rameters recorded on the transducer’s nameplate. Each trans- ducer is factory-configured for a specific gas and flow range, pressure differential, temperature range and mounting position.
2.Do not locate the transducer in areas subject to sudden tem- perature changes, moisture, drafts or near equipment radiating significant amounts of heat. Make sure to allow adequate space for cable connectors and wiring.
3.Make sure the location meets the minimum number of recom- mended pipe diameters upstream and downstream of any NPT or 1/2-inch process connection. A minimum of two inches is always recommended.
4.If the gas contains any particulate matter, install an in-line fil- ter prior to the transducer. Recommended filter size: 15 mi- cron for flows of 10 to 30 slpm, 30 micron for above 30 slpm.
5.If the transducer is mounted in any position other than horizontal and it was not calibrated specifically for that position, contact Si- erra’s Customer Service Department for instructions.
6.For meters, if a potential over-flow condition exists, insert a valve or critical orifice in the line to limit flow to approxi- mately 25 percent above the full scale range of the meter.
7.For controllers, use a properly-sized pressure controller and verify the controller orifice size is the smallest in the system. There can be no restrictions (such as valves, tubing or piping internal diameters, reducers, etc.) upstream or downstream of the controller less than the valve orifice diameter.
8.Confirm that the transducer o-ring material is compatible with the gas to be measured.
