The Calibration menu shown in Figure 35 provides access to all the calibration functions for the SVI II AP. If a change is made in the Air-To-Open/Air-To-Close configuration option or if you move the SVI II AP to a different valve or make any change to the valve position linkage, you must run...

Don't forget the transmitters only report a pressure differential. If the fluid is subject to temperature or composition gradients, or unexpected flow patterns that alter the reported pressure, you can only estimate the actual fluid level.

Your IMG-202404821_0 appears to show the flush ring mounted on the back of a flanged diaphram seal.

You need to contact your supplier, and read the maintenance literature. Sealed capillary systems are not meant to be flushed.

You'll need to provide a scetch of your circuit and your proposed contactor

Boiler feed water pumps are subject to a vast number of process variables, so you'll have to spend a lot of time getting familiar with the actual operating environment.

Make sure all air is flushed out of the instrument tubing using the bleed vents at the transmitter, to insure stable zero setting. 5% to 6% error at low flow conditions is not uncommon in operating plants.

What is the pipe size, details of your orifice plate, and the vendors meter calculation, and piping layout

You may not be able to disconnect wiring for trouble shooting, so how would you measure current

Measuring current in a traditional vehicle, you'll need to have clamp on access, for both moderate and high currents. With electric vehicles, you'll have to consult the manufacturers recommended practice and test equipment.

The first time I saw such damage, it looked like it was intentionally hammered on an anvil, not unlike the op's image

The sheath thickness of Pt RTDS'a is less than 0.1mm and when damaged your first impression is how could it be so damaged. When flow induced resonances are involved, the tip acceleration can easily become 50-100 G's high frequency vibration. The sensors don't last long at that level.

First determine if flow induced resonance conditions are likely, just to identify possible cause and future risk you might be dealing with. All you need are nominal dimensions of your thermowell, and nominal fluid velocity, presumed liquid. Some applications require RTD measurements, especially...

Witnessed failed Pt RTDS that slip fit within the well, due to excess vibration. RTD's are limited to thermowell tip accelerations exceeding 10 G's . Conventional T/C can take 20-30 G's before failure. Thermowell cracking due to fatigue failure is another issue. With key dimensions of the TW...

Check the logic or relay circuits controlling the startup valve and the fuel valve for normal operation.

Apart from calibration drifts of thermocouples and RTD's, temperature sensors fail as an open circuits either gradually or instantly. Open circuit thermocouples read low, open circuit RTD's read high. As WTF mentioned the vendor is not using effective logic when multiple sensors are involved...
