Product Usage Instructions

Safety Precautions

Before installing or using the In-Line Paddle Wheel Flow Meter
Sensor, ensure you follow these safety precautions:

• De-pressurize and vent the system before installation or
  removal.

• Confirm chemical compatibility before use.

• Do not exceed maximum temperature or pressure
  specifications.

• Always wear safety goggles or a face shield during installation
  and service.

• Do not alter the product construction.

Installation Guidelines

Follow these guidelines for proper installation of the flow
meter:

• Always hand tighten, avoid over-tightening.

• Avoid using tools as they may damage the product.

• Ensure there is enough straight pipe length to avoid turbulent
  flow.

• Install a Bag Filter or Y Strainer upstream to protect the
  paddle wheel from damage.

Maintenance and Care

To ensure optimal performance and longevity of the flow
meter:

• Avoid subjecting the instrument to water hammer or pressure
  spikes.

• Periodically pressure test the system with water before initial
  start-up.

• Avoid flushing the pipe with compressed air after installation
  to prevent damage to the ceramic shaft.

FAQ

Q: Can the TK Series flow meter be installed vertically?

A: Yes, the TK Series can be installed in either a horizontal or
vertical direction. Ensure there is sufficient straight pipe length
for accurate readings.

Q: What should I do if I encounter a pressurized system

warning?

A: If you encounter a pressurized system warning, make sure to
vent the system prior to installation or removal to prevent
equipment damage or injury.

Q: How can I protect the paddle wheel from damage?

A: Install a Bag Filter or Y Strainer upstream to avoid damage
from solids or fibers. Do not exceed the specified particle size
limits to prevent warranty void.

Do Not Use Tools
Use of tool(s) may damage produced beyond repair and potentially void product warranty.

Personal Protective Equipment (PPE)
Always utilize the most appropriate PPE during installation and service of Truflo products.

WARNING

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 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 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.

Truflo® — TKM Series
In-Line Paddle Wheel Flow Meter Sensor

Industry’s Most Accurate & Reliable Paddle Wheel Flow Meters

The TK Series insertion 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.

New ShearPro® Design
? Contoured Flow Profile ? Reduced Turbulence = Increased Longevity ? 78% Less Drag than Old Flat Paddle Design
