FPM100 User’s Manual
Keep in mind that the rated burst pressure of the pressure transducer is 2.4 to 3 times the
maximum measurement pressure of the transducer. If the pressure transducer will experience
pressure spikes in excess of the transducer’s maximum measurement pressure, use of a
Pressure Snubber (PT-SNUB-01) accessory is highly recommended. The snubber will dampen
pressure spikes that will be seen by the pressure transducer.
Please refer to the installation instructions packaged with the pressure transducer accessory
for detailed installation instructions for the transducer itself.
2.4.2 Tank Level Measurement Applications
The pressure transducer should be mounted to a properly sized fitting on the side of the tank
as close as possible to the tank bottom. The pressure transducer cannot provide an accurate
measurement when the fluid level is below the level of the pressure port of the pressure
transducer. Please refer to Figure 4 below for an example of pressure transducer mounting on
the side of the tank.

It is highly recommended that a ball valve be mounted between the pressure transducer and
the tank. This allows the pressure transducer to be serviced without draining the tank. Please
refer to Figure 5 below for an example of the installed ball valve.
