ADDENDUM TO LEVEL RADAR INSTALLATION AND OPERATION INSTRUCTIONS: 7.02182.77.00 Compliance with U.S.A. FCC Part 15 Rules (FCC ID JH5-70) and FCC Part 90 Rules (JH5BM70) The BM70A Level Radar complies with Part 15 of the FCC Rules when installed in totally enclosed metal tanks. A label is affixed to the instrument as shown below: ` When installing the metal, “horn” antenna versions with metal gaskets (all metal, metal-sheathed, or spiral-wound metal gaskets), only normal installation procedures should be observed. When installing a device with a “Wave-Stick” PTFE antenna or with a non- metallic gasket, the installation must include the shielding strip (item “C) and the strap retainer (item “S”) shown in Section “6.1.8 Ultimate installation on the tank “ on page 23. Also, the flange bolt holes, top and bottom, must be completely covered by the bolt heads and nuts which may require the use of flange bolts and flange nuts or appropriately-sized flat washers. The item referred to by the asterisk should read – “ * required for European radio approvals and United States FCC Part 15 approval for Wave-Stick version or FCC Part 15 approval when installed with non-metallic gaskets”. When installing the BM70A in other than totally enclosed metal tanks, a site- specific license under FCC Part 90 Rules must be obtained as Krohne’s FCC identifier - FCC ID JH5BM70. Contact Krohne for procedure to obtain license. Please note: changes or modifications not expressly approved by Krohne, could void the user’s authority to operate the equipment. FCC ID JH5-70 Krohne Level Radar When installed in totally enclosed metal tanks, this device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference which may cause undesired operation.

From: Robert J. Ungar To: '[email protected]' Cc: Terry Mahn Sent: Wednesday, April 10, 2002 4:34 PM Subject: BM70 As we discussed, this morning I spoke to both Julie Knapp, Deputy Chief of OET and, at his suggestion, Fred Thomas, the FCC's IRAC representative concerning the scope of the Part 15 restricted band waiver granted to Krohne for its BM70 and BM702 devices. The bottom line is that changes to these devices will still come under the waiver as long as: 1)testing shows variants of the BM70 devices to be within Part 15 limits and 2) variants of the BM702 operate in a manner consistent with the test data filed with the Krohne waiver request. Both devices can only be certificated under Part 15 for use in steel tanks. According to Barc Beahm the BM70A is just the lineal descendent of the BM70 with accumulated changes over the last ten years. It is essentially the same device which sweeps through the same restricted bands and which, as you know, still complies with the Part 15 technical standards. Please let me know if you have any questions.

The model number covered by this report is BM 70 A. This report is designed to demonstrate the compliance of this device with the requirements outlined in 47 CFR Part 15 using the methods outlined in 47 CFR Part 2. The BM 70 A, in its most general form, is an FCC Part 90 licensed device. This application is an attempt to gain certification as an unlicensed transmitter under Part 15 using a waiver for operation in the band 9-10GHz issued by the FCC to Krohne on October 26, 2001 (included). As per the conditions of the waiver, this application is only for those installations of the BM 70 A which are inside a steel tank. The BM 70 A Level-Radar level gauging system can be implemented in various different configurations, each consisting of a combination of certain options. The particular options considered in this application for certification are listed below: (those options used during testing are indicated with an asterisk) Power Supply: 1) 24V DC * 2) 115/230V AC * Antenna Type: 1) Wave-Stick * 2) 8” Horn (Type 4) 3) 6” Horn (Type 3) * 4) 4” Horn (Type 2) 5) 3” Horn (Type 1) Signal Output: 1) Ex-e current output HART® * 2) Ex-i current output HART® 3) Current output 4) RS 485 + current output * 5) PROFIBUS FMS/DP 6) PROFIBUS PA 7) Foundation Fieldbus (FF) * The following factors and assumptions were considered in producing a test plan which would conservatively cover the entire range of configurations: 1) It is unlikely that there would exist differences in emissions characteristics between... a) ...the two power supply options at frequencies above 1GHz. b) ...the seven signal output options at frequencies above 1GHz. c) ...the three antenna types at frequencies below 1GHz. 2) It has been determined that three of the seven signal output options would be representative of the entire group regarding emissions characteristics: Ex-e current output HART®, RS 485 + current output, and Foundation Fieldbus. The interface options do not impact the operation of the transmitter and the three samples chosen represent the most fully featured versions of the seven available variants. FCC Application for Krohne, Inc.••FCC ID: JH5-70 •• Report No. EB1249-1 5-Apr-02 ______________________________________________________________________ _____________________________ ________________________________ Curtis-Straus LLC •• 527 Great Road •• Littleton, MA •• TEL (978) 486-8880 •• FAX (978) 486-8828 page 3 of 19 3) With regards to the voltage variation measurements, (pursuant to 47 CFR 15.31(e)) it has been determined sufficient to test the DC power supply option only. This determination was based on the fact that the AC power option delivers 24VDC power to the same 24V DC module used in the DC only configuration. 4) The sample tank used for testing can accommodate only up to a 6” horn antenna. All horn antenna testing was performed using the 6” horn. As the horn size increases, so does the gain of the antenna. Since the output of the transmitter cannot be varied, the worst-case configuration would be with the 8” horn. To compensate for the use of the 6” horn during testing, an out of tank measurement was made with both the 6” and 8” horns. This allowed us to generate a correction factor to determine the compliance of the worst-case 8” horn configuration. The resultant test plan is shown below: 1) Determine a correction factor to be added to the emissions measurements taken at the fundamental operating frequency of the BM 70 A w/ 6” Horn, in order to represent the emissions at the fundamental operating frequency of a properly implemented BM 70 A w/ 8” Horn. Determine the correction factor by taking measurements at the fundamental operating frequency of both antennas operating in “open air” with identical (maximized) positions relative to the receiving antenna. 2) Perform radiated emissions scans from 1 to 40GHz of both the 6” Horn, and Wave-Stick antennas using either power option and any communication option. 3) Perform radiated emissions scans from 30MHz to 1GHz of the following three configurations: a) AC supply; Wave-Stick; Ex-e current output HART® b) DC supply; 6” Horn; Foundation Fieldbus c) DC supply; 6” Horn; RS 485 + current output 4) Perform six conducted emissions scans from 450kHz to 30MHz consisting of both the DC supply and AC supply each in conjunction with the three representative signal output alternatives. 5) Perform the voltage variation measurements with any configuration, which has DC as its power supply option. Calculation of Duty Cycle Correction Factor 47 CFR 15.35(c) provides for an alternative method of representing a measurement of an emission above 1000MHz. Under normal circumstances, measurements of emissions above 1000MHz are taken with an average detector. In cases where it is not possible to use an average detector, it is acceptable to use a peak detector, provided that a correction factor is determined which correlates a peak measurement and an average measurement by way of a duty cycle calculation. The worst-case duty cycle is given as the maximum percenta…
