Vent Cleaners (VC)

Industry-Leading Manual Vent Cleaner for dP Meter Pressure Tap Maintenance 

Vent cleaners are a simple, field-proven accessory used to manually clear the pressure taps (piezometer connections) on static-tap or corner-tap differential producer primary flow elements. By removing debris or buildup at the tap, they help prevent obstructions in the pressure-sensing line(s) between the meter and transmitter, supporting more reliable dP signal performance over time.

Each tap location uses its own vent cleaner (one per piezometer). For standard HVT-CI (cast iron) meters, there is no difference between high- and low-pressure tap vent cleaners; installation and use are the same for both sides.

Key Advantages Include:

• Built-In Isolation: Optional isolation ball valves support safer, more controlled maintenance.
• Fits Exact Meter Geometry: Precision component design matches the meter’s tap geometry to assure proper cleaning.
• Multiple Length Options: Different lengths are available to suit varying meter layouts and access needs.
• Static or Corner Tap Designs: Supports both common tap configurations used on dP primary elements.
• Custom Solutions for Tight Spaces: Custom designs are available for difficult or space-constrained installations.

Typical applications include wastewater, raw water, municipal water systems, and potable water services—anywhere pressure taps and sensing lines may be prone to plugging and require periodic manual clearing to maintain dependable measurement.

Installation Overview

Installation is straightforward: remove the plastic thread protector(s), apply Teflon tape or pipe compound to the threads, insert the threaded end into the piezometer connection on the primary flow element, and tighten securely enough to eliminate leakage (torqueing is not required).
