2. WELL OR TANK U BUBBLES FIGURE 2 7 Bubbler System 2 8 1 Bubblers By using a hollow tube and blowing dry nitrogen into it measuring the back pressure generated by the depth within the liquid a reasonable measurement of liquid level may be made The major advantage of this method is that in extremely harsh environments the tube which is less expensive than the pressure sensor is sacrificed to corrosion The tube may also be immersed in high temperature liquids with application of the right materials The acquisition cost is higher than a submersible sensor due to the addition of the Nitrogen or Dry Air source plus installation and maintenance Routine Pressure Level Sensor Application Handbook Revision J4 Sensing 96 Druck maintenance is required in order to maintain reliability The accuracy is not quite as good as the directly submerged sensor This method is also used as shown in Figure 2 8 in open channel flow measurements where hydrostatic head is measured in flumes and weirs ESA lt TUB O O O FLACA O ee 00 O O FIGURE 2 8 Open Channel Flow Using Bubbler System 2 8 2 GE Sensing offers a range of pressure sensors suitable for use with bubbler systems including the UNIK 5000 Series the RTX1000 Series Smart Transmitters with HART protocol and TERPS Series high accura
3. DEPTH OF WATER INDICATED FIGURE 2 1 Manual Logging Graduated Stick Manual Logging Dip Meter A variation is the use of a dip meter that uses a graduated cable and is normally wound on a spool When the end of the cable equipped with electrodes touches the water the circuit is completed and a galvanometer registers continuity Some diameters have an audio tone that beeps when the circuit is completed at the surface of the water GRADUATED ELECTRICAL CABLE GRADUATED ELECTRICAL CABLE DEPTH BELOW GROUND INDICATED Cc ELECTRODES FIGURE 2 2 Manual Logging Dip Meter Pressure Level Sensor Application Handbook Revision J4 Sensing Druck 2 3 Visual Sight Gauges A graduated column of liquid may be used to determine liquid level and are typically located outside of the tank The level is visually checked and recorded Some of these devices are quite inexpensive and no more reliable than the person taking the reading In some circumstances the marking becomes faded or the sight glass becomes clouded making it difficult to read the level It is also a local indication The use of fiber optics allows remote readings to be made but increases the cost dramatically 2 4 Floats and Switches A major step forward from the manual and visual systems It is possible to set up alarms actuated by switches This enables the system

47. 1 S DHA JC Groby Leicester 22nd December 1988 Dear Sirs CORROSION OF 316L STAINLESS STEEL PRESSURE SENSORS With reference to the recently received pressure sensors you supplied for metallurgical examination I enclose our preliminary comments and findings Sensor 1 The first sensor was supplied as one half of a longitudinal section which had been acid etched to reveal the weld profile This acid etching had obviously caused some additional corrosive attack on the component Regardless of this fact it is apparent that corrosive attack had taken place in service in the stainless steel body under the Hastelloy diaphragm and also at the heat affected zone of the welded joint between the diaphragm and the stainless steel body 7 i Both the diaphragm and body materials were semi quantitatively exam ned and identified as Hastelloy and 316 stainless steel respectively Sensor 2 This complete sensor was supplied in the condition from which it had been removed from service see Fig 1 There was a white crystalline deposit covering the majority of the outside of the sensor body particularly around the six inlet holes and the base of the device above the 0 ring grooves Fig 1 This deposit has been identified as predominantly chloride salts of magnesium and calcium Optical examination of the device showed that severe corrosion had occurred at the interface of the base of the component abovethe 0 ring grooves where it slips int

GE Sensing protects its submersible sensors by incorporating a filter in the nose cone see Figure 4 1 The small holes on the periphery of the front end are designed to allow any trapped air to escape as the unit is submerged Pressure containment If the mechanical integrity is important i e if the transducer leaks and that leakage could cause damage or an unsafe condition this specification is important Media compatibility This is one of the most critical and important specifications since it is a major cause of premature failure in submersible pressure sensors Often the customer is not aware of corrosive chemicals present in his application such as H2S Salt NaCl or other mild or severe acids or caustics Their water contains naturally occurring aggressive chemicals that are removed during water treatment but are present in the wells The following materials are used by the majority of sensor manufacturers 316L stainless steel Hastelloy C276 and titanium Of these materials only titanium is impervious to virtually all corrosive elements normally found in ground water and wastewater applications Many water applications include installation in sea brackish water It is recommended that 316 stainless steel not be used in sea brackish water applications Titanium is ideal for those applications where sea brackish water is anticipated Construction An all welded design provides hermetic sealing thus preventing leaks
