FB3 Sensor Dimensions:
The FB3 sensor is used for applications where the
maximum level is 50 feet. (See Specifications Page
1-2.) There is a 1 inch NPT threaded nipple on top
of the sensor for mounting on bracket or customer
provided flange.
Sensor Mounting Terms:
Whether the sensor is to be used for flow in
conjunction with a primary element such as flumes
or weirs, or used for level measurement only, there
are two terms that must be understood to mount the
sensor properly in either application.
1. The VMt is the vertical mounting distance
between zero level (zero flow level of flumes or
weirs or zero level of tank) and the bottom of the
sensor. This is the offset plus the span.
Consideration must be given when mounting the
sensor in respect to sidewalls. The distance from a
wall to the FB7 sensor is 0.875 inch per foot of VMt.
For the FB3 it is 1.5 inches per foot of VMt.
2. The HMt is utilized in flow applications. It is the
upstream horizontal distance that the sensor needs to
be placed from a reference point of the primary
element. The HMt dimension is displayed on the
2200 when programming the unit. Refer to Page 3-
12 for mounting detail for various primary elements.
