A1 Scope
This document contains information for the Gen 3 Liquid
Level Controller & includes detailed installation, operation
& repair/maintenance information for the product.
A2 Description
The Gen 3 Liquid Level Controller is designed for use in
single-phase & interface liquid control applications. The
pilot is capable of both Snap mode (on/off) & Throttle
mode (modulating). Pneumatic output can be set to
operate as Direct Acting or Indirect Acting. The mounting
body can be flipped to either Left Hand or Right Hand
Mount. The displacer may be assembled in vertical or
horizontal orientation. Changing between these options
does not require additional components nor swapping
out pilots.
A3 Definitions
Snap Mode: On/Off, discrete output. Liquid level ranges
from high point to low point, large span.
Throttle Mode: Modulating, proportional output. Holds
consistent level, with very small span.
Direct Acting: For Fail Closed (FC) aka Pressure-to-Open
(PO) Valve. Pilot provides maximum output when liquid
level reaches set point at top of span.
Indirect Acting: For Fail Open (FO) aka Pressure-to-
Close (PC) Valve. Pilot provides maximum output when
liquid level reaches bottom of span.
Left Hand Mount: With front of controller facing operator,
unit is mounted on left side of vessel. For Back Mount
applications, use this mount option due to the location of
the cover latch.
Right Hand Mount: With front of controller facing
operator, unit is mounted on right side of vessel.
Set Point: The liquid level at which the controller opens
the valve. In Snap Mode, this is at the top of the span. In
Throttle Mode, the liquid level should stay consistent at
the set point.
Span: Distance between the highest & lowest liquid level
during operation. This can be set with the Sensitivity
Fulcrum. See “Span Adjustment” below.
