Elesa+Ganter 111301 Visual Flow Indicator: HVF.66-1/4 Technical Overview

The Elesa+Ganter 111301 visual flow indicator, known as HVF.66-1/4, is designed for visual monitoring of liquid flow in hydraulic and industrial fluid systems. It allows operators to confirm flow movement directly through a transparent viewing area, making it a practical component for maintenance, diagnostics, and routine machine checks.

Product Function

The HVF.66-1/4 is a visual flow indicator with brass bosses and technopolymer ends. It is intended for bidirectional liquid flow and includes an internal rotor propeller that turns when the fluid flow reaches the minimum required rate. This visible movement helps users confirm that liquid is circulating through the line.

Technical Characteristics

The 111301 version has a G 1/4 connection, 66 mm height, 44 mm length, and approximately 74 g weight. It is associated with a maximum flow indication of 10 l/min and maximum pressure of 25 bar. The product also includes a borosilicate glass tubular window, selected for high resistance and clear flow visibility from different angles.

Why It Matters in Fluid Systems

Flow confirmation is essential in many hydraulic, cooling, lubrication, and process systems. A pump may be running, but without visible confirmation, restrictions, air pockets, or blocked lines can be missed. The Elesa+Ganter 111301 visual flow indicator gives technicians a simple way to verify flow without needing an electronic display.

Its compact G 1/4 format makes it useful in smaller lines where a robust, easy-to-read flow indicator is required. For more information about Elesa+Ganter components, check pressure rating, flow rate, viscosity range, and connection size before installation.
