Yokogawa FU20-VP-T1-NPTFPS Vortex Flow Sensor | In-line, 1-inch, Wafer, NPT

Yokogawa FU20-VP-T1-NPTFPS flow sensor specifications. In-line vortex flow sensor, 1" wafer, with NPT flanges, for liquid/gas/steam.

Product Overview

The Yokogawa FU20-VP-T1-NPTFPS is an in-line vortex flow sensor assembly from the FU20 series. The "VP" indicates a wafer-style sensor body, and the suffix specifies a 1-inch size with NPT flanged process connections. It is designed for direct installation into 1-inch pipelines to measure the flow of liquids, gases, or steam by detecting the frequency of vortices shed from a bluff body.

Technical Specifications

Key Features

• Complete Flanged Assembly:​ Sensor body with pre-attached NPT flanges for bolt-in installation between pipeline flanges

• In-line Design:​ Provides measurement representative of the full pipe flow

• Wide Application:​ Suitable for liquids, gases, and steam

• Robust Construction:​ All-welded 316 stainless steel for durability

• No Moving Parts:​ Low maintenance and high reliability

• Linear Output:​ Pulse frequency output is linear with flow rate

• Compact Wafer Design:​ Lightweight and space-saving between flanges

Applications

• Flow measurement of water, chemicals, and fuels in 1-inch lines

• Steam flow measurement for small boilers or equipment

• Air and gas flow monitoring

• General industrial flow measurement in smaller pipe sizes requiring flanged connections

Important Notes

1. This is a sensor only; it requires a separate vortex flow converter/transmitter (e.g., Yokogawa DY, YF) to generate a 4-20mA or other standard output signal.

2. Must be sized correctly for the application's fluid, flow range, pressure, and temperature.

3. Requires proper upstream/downstream straight pipe run for accurate measurement (typically 15D/5D).

4. The "NPTFPS" suffix indicates the specific type of NPT flanged connection.

5. Installation requires gaskets and correct bolting between pipeline flanges.
