[. . . ] Instruction Manual May 2008 milltronics ILE-61 Safety Guidelines: Warning notices must be observed to ensure personal safety as well as that of others, and to protect the product and the connected equipment. These warning notices are accompanied by a clarification of the level of caution to be observed. Qualified Personnel: This device/system may only be set up and operated in conjunction with this manual. Qualified personnel are only authorized to install and operate this equipment in accordance with established safety practices and standards. [. . . ] The test weight is also used to perform a test to verify that the flowmeter sensing head is level. The test rate should be 60 to 80% of the system designrate. To determine the test rate produced by a specific test weight. . . Test Rate (TPH) = Test Weight (grams) 45* grams/ TPH Alternatively, to determine the test weight required for a specific test rate: Test Weight (grams) = 45* grams x Test Rate (in TPH) 1 TPH *Use 60 grams for A-300 flowmeters. If the test weight used with an E-300 flowmeter is 7000 grams. . . = 155 TPH Test Rate = 7000 grams 45 grams/TPH Note: Use metric tons per hour (t/h) or short tons per hour (STPH) as applicable for TPH. LVDT Output Zero Adjustment 1. Connect a voltmeter across the LVDT green and yellow (or yellow and white) wires. With no load applied to the sensing plate, observe 0. 10 V AC on the voltmeter. Note: If the LVDT output is 0. 10 to 0. 05 V AC, skip to span test, otherwise, proceed as follows: a. Loosen the locknut on the LVDT threaded core. b. Turn the core in/out of the LVDT until 0. 10 to 0. 05 V AC is obtained. c. Tighten the locknut, ensuring the measured value is maintained.

Gently push the sensing head moving beam to the right. The LVDT output should increase steadily until a level of 0. 75 to 1. 0 V AC is achieved. Gently push the sensing head moving beam to the left. The LVDT output should decrease steadily until zero is reached and then increase to 0. 25 to 0. 50 V AC. Ensure the LVDT output always returns to 0. 10 to 0. 05 V AC, (on the right hand side of zero), when pressure on the moving beam is released. Note: The LVDT core must not contact the inside of the LVDT over the range of core travel. The actual LVDT core travel during this procedure is less than 3 mm (1/8"). 0. 750 to 1. 000 0. 050 to 0. 150 0. 015 to 0. 500 Sensing Head Level Test 1. With the voltmeter still connected to the LVDT output, hang the test weight directly off the sensing plate. Observe the display value does not change by more than 0. 01 V AC. Note: If the change is greater than 0. 01 V AC, adjust the sensing head level until the change with and without the test weight on the sensing plate is less than 0. 01 V AC. Remove the test weight and readjust the LVDT output zero, if necessary. If this procedure is performed after the integrator is calibrated, a new integrator zero and span calibration, span adjust, and Factoring (if required) should be performed. sensing plate changes < 0. 01 V AC test weight 7ML19985CX01 Milltronics ILE-61 ­ INSTRUCTION MANUAL Page 9 Integrator Calibration Refer to the flowmeter integrator instruction manual for integrator calibration instructions. To apply the test weight for the span calibration: 1. [. . . ] Record the integrator rate display value associated with each test weight applied to the flowmeter. If all the recorded display values are accurate, the flowmeter measurement is linear. For an E-300 flowmeter Design Rate of 200 TPH, the following three test weights could be used: · 9000 g (19. 82 lb. ) = 100% Design Rate = 200 TPH · 6750 g (14. 87 lb. ) = 75% Design Rate = 150 TPH · 4500 g (9. 91 lb. ) = 50% Design Rate = 100 TPH If non-linear results are obtained, ensure: · at no flow, the moving beam does not rest on the zero stop bolt. · at 150% Design Rate, the moving beam does not reach the full flow stop bolt.
