Elesa+Ganter 111317 Visual Flow Indicator: HVF.92-3/8 NPT Technical Overview

The Elesa+Ganter 111317 visual flow indicator, model HVF.92-3/8 NPT, is a compact fluid monitoring component designed for applications where operators need a clear, mechanical view of liquid flow. Unlike HVF-E versions with an integrated flow-meter sensor, this product type focuses on direct visual confirmation through the transparent indicator body and internal rotor movement.

Technical Specifications

The HVF.92-3/8 NPT version has a 3/8 NPT connection, 92 mm height, 60 mm length, 40 mm body width, 36 mm h1 dimension, and 28 mm s dimension. Its maximum flow rate is 20 l/min, and the maximum pressure rating is 15 bar. The listed starting flow values vary according to fluid viscosity, which is important when the component is used outside clean water-like operating conditions.

The unit is built with technopolymer ends and brass bosses. Its transparent body allows operators and maintenance teams to check the rotor visually without opening the system. This makes the Elesa+Ganter 111317 visual flow indicator useful for quick inspection points on machinery, cooling lines, lubrication circuits, and fluid distribution systems.

NPT Connection Advantage

The NPT thread format makes this model practical for systems where conical pipe threads are specified. This is particularly relevant in installations that follow North American piping standards or equipment designs where NPT fittings are already used. Choosing the correct thread type helps improve sealing reliability and avoids unnecessary adapters.

Operational Considerations

Because the HVF.92-3/8 NPT is a visual indicator, its effectiveness depends on clean fluid and proper placement. The rotor should remain visible, and the indicator should be mounted where technicians can inspect it easily. Before installation, the circuit should be flushed to remove particles that could affect rotor movement. It is also advisable to consider viscosity, pressure drop, and actual flow conditions before final selection.

Elesa+Ganter 111317 FAQ

What is the Elesa+Ganter 111317 HVF.92-3/8 NPT used for?

It is used for visual monitoring of liquid flow in industrial systems, especially where a 3/8 NPT connection is required.

Does this model include a flow-meter sensor?

No. This model is a visual flow indicator. For sensor-based monitoring, HVF-E versions should be considered.

What is the maximum flow rate?

The maximum flow rate is 20 l/min under the stated reference conditions.

What is the maximum pressure rating?

The maximum pressure rating is 15 bar.

Why is the NPT version important?

The NPT version is suitable for systems designed around tapered pipe threads, helping match the indicator to existing piping standards.
