With the flowmeter housing installed, remove the ILE-37 sensing head cover. Loosen the four ILE-37 mounting bolts. Place a spirit level on the flat top of the ILE-37 frame: adjust the sensing head level by rotating it, and retighten the mounting bolts.
Base M ount With the flowmeter housing installed, mount the ILE-37 to a rigid support structure. With the outer gasket in place, bolt the ILE-37 to the housing. Adjust the sensing head levelling hardware provided, to establish level in both horizontal planes.

Run additional conductors: - from SF500 terminal 12 to conditioner terminal block marked "Integrator +EXC" - from SF500 terminal 13 to conditioner terminal block marked "Integrator –EXC" For further connection information on specific LVDTs, consult Milltronics. ♦ Note: Shields are common, but not grounded to chassis. Run cable shields through SHLD terminals and ground at Integrator only.

After you have removed and replaced the range spring, recalibrate the flowmeter and integrator. (See the Integrator Manual, CALIBRATION section, for details.) Perform the LVDT output Zero procedure. Perform an integrator Zero and Span calibration. Perform a Span Adjust and Factoring as required. Page 16 ILE-37 Sensing Head – INSTRUCTION MANUAL 7ML19981CW01...
Troubleshooting Every Milltronics ILE-37 Sensing Head is subjected to extensive quality assurance procedures to ensure the highest possible degree of quality, reliability, and performance is achieved. The following listing indicates the probable cause, and proper course of action to be taken should the specified fault symptom occur.
Some integrators are equipped with a linearization function to compensate for non-linear material flow patterns. Stand-alone linearizing devices are also available for this purpose. Electronic linearization should not be used to correct non-linear test weight results. Page 18 ILE-37 Sensing Head – INSTRUCTION MANUAL 7ML19981CW01...
