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
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.
