2.4 INSERTION INSTALLATIONS.

The Model 399VP sensor has forward and rear facing 1 in. MNPT process connections for pipeline installations (see Figure 2-4 or 2-5) and flange connections. The Model 399VP is also suitable for side-of-tank installation. The Model 399VP must be mounted at least 10° above the horizontal (see Figure 2-4).

NOTE

Large pipe wrenches must not be used to tighten the sensor into a flange or other type of mounting.
