    • Flow Transmitter-to-Sampler Connect Cable 1.4 The Submerged Probe The submerged probe, used by the 3020 Flow Transmitter as a level sensor, is shown in Figure 1-2, and is mounted in the flow stream. It measures liquid level by sensing changes in hydro- static pressure as level increases or decreases above it.
