ProScan In-Line Process Sensor
User Manual

Installation
ProScan has a conventional sanitary clamp connector that attaches directly to a tee or saddle in the
process line or vessel. ProScan comes in standard 1.5, 2, 2.5 and 3 inch sizes.
You can install ProScan in a wide variety of configurations, including vertical and horizontal process lines
and tanks. To optimize the performance of the sensor, it is important to:

keep the deadleg as short as possible on the tee connection, and

choose an installation site that minimizes air or sediment from collecting on the sensor’s lens.
Deadleg
To minimize deadleg, cut the tee back so the ProScan lens is as close as possible to the process stream.
In most cases, it is possible to cut the tee back and have a resulting deadleg of 1 to 2 inches. The shorter
the deadleg, the better.
Installation Site
Select an installation site and orientation that minimizes the possibility of air or sediment interfering
with the sensor’s readings.
Vertical
Vertical sections of process lines are excellent installation sites, whether the flow is down or up.
Horizontal
Another excellent installation site is a 90-degree elbow on a horizontal line. In this case, position the
ProScan device so the fluid flows directly at the sensor’s lens.
Straight Sections
If installed on a straight section of horizontal process line, place ProScan so it looks sideways into the
process stream, not up or down.
Installations Not Recommended
Two installations not recommended are:

on the top of horizontal process lines, where air has a tendency to accumulate, and

on the bottom of horizontal process lines, where sediment can accumulate.
Clamp Connection Gasket
The clamp connection requires a gasket between ProScan and the tee. In most cases, the customer
provides the gasket and the tee. Customers can purchase these products from AW Gear Meters, if
necessary.
