    (6) The strainer should be located upstream of, and as close to the meter as possible. (7) Since the sensor in ULTRA UF-II operates on the principle of sensing changes in magnetic flux density, it must be isolated from the influence of any external magnetic flux. In order to minimize the influence of...

  • Page 16: Preamp-To-Receiving Instrument Hookup With Register Type U8

    An OVAL receiving instrument can be coupled directly, but instruments in general which are designed to accept a voltage signal input require a load resistor RL connected in series for voltage conversion. Since the voltage signal level varies with the load resistance value, determine the load resistance value by referring to the receiving instrument specifications and the acceptable load resistance range shown below.

    B-525-6-E 10. DISASSEMBLY AND INSPECTION ◎ Although it depends on individual operating conditions, periodic disassembly and inspection should be performed at least once a year. CAUTION 1. Because the UF-II Flowmeter is a precision industrial instrument, disassembly and inspection should be performed indoors as a rule. If it is desired to disassemble and inspect it as installed in the field, an important precaution to remember is to reduce the internal pressure of the piping assembly to a safe level, shut off valves upstream and downstream of the meter fully, drain the...
