Page 7: Installation
II. Installation A. Enclosure & Mounting Details The MS3500E/3510E enclosure is fabricated in carbon steel with a baked-on, high-build epoxy coating. The unit has a hinged door that is secured, when shut, by screw-down clamps that discourage unauthorized tampering. The enclosure is constructed to NEMA 4X (IP 66) weatherproof standards, making it suitable for the most rigorous of outdoor environments. -
Page 8: Battery Installation
B. Battery Installation The MS3500E/3510E instrument uses six 1.5V, AA size batteries, connected in series, as a primary power source. While any AA size battery can be used, Duracell or Procell Type MN1500 or PC1500 batteries are required to meet the intrinsic safety certification requirements. Since the MS3500E/3510E operates in a low power consumption mode between readings, battery life will be a function of the reading interval and measurement time cycle set by the user. -
Page 9: 4-20Ma Loop Installation
C. 4-20mA Loop Installation The MS3510E is provided with a 4-20mA communication outlet that allows continuous, real-time integration of ER corrosion data with other process parameters in the main plant computer. The 4-20mA outlet port is a 2-pin military connector (MIL 1 4S-9SF) on the base of the unit, marked 4-20mA. -
Page 10: Probe-Instrument Connection
The female connector (MS3106E145-6S) mates with the probe, or HA700110-5 probe adaptor, and the male connector mates with the central terminal on the base of the MS3500E/3510E unit. -
Page 11: Data Download Connection(S)
If a serial port is unavailable on your PC and you wish to connect the MS3500E to your PC via a USB port, you may use a serial to USB converter. This converter is not included with the instrument, but may be purchased separately at major electronics retailers. -
Page 12: Setup And Operation
III. Setup and Operation A. Main Menu Overview Once the batteries are installed in the MS3500E/3510E, the instrument screen may be activated by pressing either of the keys on the front panel. The company name “METAL SAMPLES” and software version will appear, then after a few seconds will automatically change to the first of the function screens that constitutes the main menu. - Page 13 As explained, each function screen gives access to a submenu, the purpose of which is briefly described below: MEASURE PROBE. This will override the normal interval of logging readings to allow a spot check reading to be obtained on screen. MEASURE METER PROVER.

Page 31: Data Interpretation
I. Data Interpretation The MS3500E supplies corrosion data in several formats: • Probe Reading (‘Probe Life Units’) • Metal Loss • Corrosion Rate • 4-20 mA (MS3510E) 1. Probe Reading This information is available through the “MEASURE PROBE” (see p. 13) menu for current reading, and through the “VIEW STORED DATA”... -
Page 32: Metal Loss
If a partially consumed probe is attached to an MS3500E/3510E to perform a logging sequence, the MILS value shown will be an overestimation of metal loss at the present locations by an amount equivalent to the thickness loss prior to the commencement of logging operations. -
Page 33: 20Ma Output
4. 4-20mA Output The current loop on the MS3510E unit will send a continuous measure of the current probe reading. This is a linearized signal that can easily be converted to ‘probe life units’ (PLU) at the receiving device by applying the following simple algorithm: (A-4) 1000 PLU = ...... -
Page 34: Er Technique - General
IV. ER Technique - General A. Measurement Theory The reduction in cross-sectional area of an element of metal or alloy as it corrodes is accompanied by a corresponding increase in the electrical resistance of the element. The relationship is given by: R = p x L/A ........(6) R = element resistance P = specific resistivity of the element alloy... - Page 35 Figure 5. Temperature Compensated Element The resistance of both the exposed element (R ) and reference element (R ) are equally influenced by temperature. Consequently, the resistance ratio of the exposed to reference elements is a function only of the loss in metal thickness on the exposed element, and therefore of corrosion. This resistance ratio (R ) is measured either periodically with a portable instrument, or continu- ously with a variety of continuous, automatic recording/data logging instruments and read as percentage...

Page 36: Er Sensing Elements
B. ER Sensing Elements Electrical resistance probe elements are offered in a variety of thicknesses and geometries. The most common are illustrated below: Wire Loop Cylindrical Tube Loop Flush Figure 7. Element Styles Tubular loop elements are constructed from thin-walled tubing. Their small cross-section allows fast response at low corrosion rates. - Page 37 The mechanism for sealing elements into probe bodies varies. For example, the cylindrical type elements are sealed with an all metal weld, whereas flush elements are sealed with an epoxy seal. The sealing mechanism of the element is a primary factor in determining the temperature and pressure rating of an ER probe.

Page 38: Er Element Performance
C. ER Element Performance The basic ER measurement gives percentage of metal thickness loss and is a function of the original element thickness. Essentially, total metal loss and corrosion rate are given by the following functions: X x K ............(7) 1000 ) x K x 365 .......... - Page 39 Table 3. K Factors Some of the newer instruments, the MS1500E and MS3500E/3510E in particular, perform metal loss and corrosion rate calculations automatically and display these as a direct reading. These instruments contain a selectable library of element geometries that, once selected, are automatically fed into metal loss corrosion rate calculations.

Page 42: Er Probe Body Design
D. ER Probe Body Design ER probe bodies may be made in almost any design and material. Metal Samples frequently supplies custom probe designs for atypical applications. However, a standard range of designs are available that will cover the majority of uses. These standard designs are discussed in the following paragraphs. The fixed length probe, which has a body constructed in 316L stainless steel, is a general purpose probe construction. - Page 43 Retractable probes are the industry standard in refinery and petrochemical plants. The probe body is constructed in 316L stainless steel and compromises a one inch FNPT packing gland with a cylindrical probe shaft. Four basic probe lengths are available: 18", 24", 30", and 36". The actual insertion depth into the system varies depending on the mating pipe.
- Page 44 The retrievable probe is widely used in the oil and gas production and transmission industry and is part of a specially designed retrievable system. The probe is carried on a specially designed plug and in- serted through a welded or flanged access fitting as shown in Figure 12. The retrievable probe, which is normally constructed in AISI 316L stainless steel, can be inserted and removed from systems operating up to 3600 psi without system shutdown.

Page 46: Appendix B - Testing The Ms3500E/Ms3510E With The Er Meter Prover
ER Meter Prover An ER Meter Prover is provided to allow routine checks of the MS3500E/MS3510E instrument. The ER Meter Prover simulates a Wire Loop type ER probe at a fixed value which is printed on the Meter Prover label (as shown below.) - Page 47 It is important to note that the ER Meter Prover is only a check probe used to verify general instrument operation. It is not a calibration standard. The measured value may differ from the listed value as explained in step 3 above. It is also important to note that each ER Meter Prover is serialized to match the instrument it is shipped with, and its measured value may differ if it is used with another meter.
