truflo TK3P Series In Line Paddle Wheel Flow Meter Sensor Instruction Manual

Install the sensor in a horizontal or vertical direction with adequate straight pipe lengths.
Use a Bag Filter or Y Strainer Filtering Device upstream to protect the paddle wheel from damage.

Avoid flushing the pipe with compressed air after installing the Flow Meter to prevent damage to the ceramic shaft.

Usage Tips

Maintain a minimum of 10x pipe diameters upstream and 3x pipe diameters downstream for optimal performance.
Avoid intensified turbulent flow that can affect readings by ensuring adequate straight pipe lengths.

Frequently Asked Questions (FAQ)

Personal Protective Equipment (PPE)
Always utilize the most appropriate PPE during installation and service of Truflo® products.
Pressurized System Warning
Sensor may be under pressure. Take caution to vent system prior to installation or removal. Failure to do so may result in equipment damage and/or serious injury.

Please ensure that the Instruments are not to be subject to water hammer or pressure spikes! Always Pressure Test System with H2O Prior to Initial Start-Up
Before installation be certain the appropriate instrument has been selected considering operating pressure, full scale pressure, wetted material requirements, media compatibility, operating temperature, vibration, pulsation, desired accuracy and any other instrument component related to the service application including the potential need for protective attachments and/or special installation requirements. Failure to do so could result in equipment damage, failure and/or personal injury. Ensure only qualified personnel are permitted to install and maintain this instrument.

Pressurize System Warning
Sensor may be under pressure, take caution to vent system prior to installation or removal. Failure to do so may result in equipment damage and/or serious injury.

Please Ensure Full Pipe
TK Series can be installed in a horizontal or vertical direction. Please ensure enough length of straight pipe to avoid intensified turbulent flow that can effect readings.
Min 10x Pipe Diameters Upstream 3x Pipe Diameters Downstream (See Page 11)
A Bag Filter or Y Strainer Filtering Device upstream to Avoid the Paddle Wheel from being damaged by the solids or fibers – max 10% Particle Size – Not to Exceed .5mm Cross Section or Length. Please do not flush the pipe after the Flow Meter is installed with compressed air this may damage the ceramic shaft and will void warranty.

Product Description

The TK Series in-line plastic paddle wheel flow meter has been engineered to provide long-term accurate flow measurement in tough industrial applications.
The paddle wheel assembly consists of a engineered Tefzel® paddle and micro-polished zirconium ceramic rotor pin and bushings. High performance Tefzel® and Zirconium materials have been selected due to their excellent chemical and wear resistant properties.
