Yokogawa FU20-05-T1-NPT Flowmeter | Insertion Turbine, 1" NPT

Yokogawa FU20-05-T1-NPT insertion turbine flowmeter. Key specs: 1" NPT, pulse output, 316L SS. For liquid flow measurement.

Product: Yokogawa FU20-05-T1-NPT Insertion Turbine Flowmeter

The Yokogawa FU20-05-T1-NPT is an economical, insertion-type turbine flowmeter designed for general-purpose flow measurement of clean, low-viscosity liquids in pipes. It is ideal for applications where cost-effectiveness and easy installation are priorities.

Key Features

• Easy Installation:​ Can be installed via hot-tap (under pressure) or with the process shut down, minimizing downtime.

• Low Cost of Ownership:​ Simple design and low maintenance requirements.

• Wide Rangeability:​ Suitable for a variety of flow conditions.

• Compact Electronics:​ Integral preamplifier for signal conditioning.

Technical Specifications

• Model:​ FU20-05-T1-NPT

• Type:​ Insertion Turbine Flowmeter

• Process Connection:​ 1" NPT male

• Insertion Length:​ Specific to pipe size. The "-05" typically indicates a nominal 0.5" diameter sensor head, but insertion depth must be specified for the pipe OD.

• Body & Wetted Parts:​ Stainless Steel 316L

• Rotor Bearing:​ Typically tungsten carbide

• Operating Temperature Range:​ -20 to 120 °C (-4 to 248 °F) [Confirm for specific model]

• Operating Pressure Rating:​ Up to 2 MPa (20 bar / 290 psi) at 20°C

• Flow Range:​ Dependent on pipe size and fluid properties. Requires selection based on application.

• Output Signal:​ Pulse (frequency proportional to flow rate)

• Power Supply:​ Typically 5-24 V DC

• Electrical Connection:​ Integral cable or conduit entry (specify option)

Function

The sensor, inserted into the pipe, has a freely rotating turbine wheel. Fluid flow causes the turbine to spin at a speed proportional to flow velocity. A magnetic pickup detects the rotation and generates a pulse frequency output, which is converted to a flow rate.

Typical Applications

• Water and wastewater flow monitoring

• Cooling water measurement

• Chemical injection and dosing

• Industrial process water lines

Important Note

Critical:​ The FU20-05-T1-NPT​ is a base model code. Accurate specification requires defining the insertion length​ based on the pipe outside diameter (OD). The flow range, accuracy, and minimum/maximum linear flow rates are all dependent on the specific pipe size and fluid properties (viscosity, density). Always consult the selection guide for proper sizing.

Note: Specifications are for product identification and comparison. This is a general-purpose device. For accurate application, you must provide pipe size, fluid, and flow rates to determine the correct insertion length and verify performance. Consult the official Yokogawa FU20 datasheet.
