truflo TKM Series In Line Paddle Wheel Flow Meter Sensor User Manual

Safety Information
Before installation or removal, ensure to depressurize and vent the system. Confirm chemical compatibility before use, and do not exceed maximum temperature or pressure specifications. Always wear safety goggles or face shield during installation and service, and do not alter product construction.

Personal Protective Equipment (PPE)
Always use appropriate PPE during installation and servicing of the Truflo products.
Pressurized System Warning
Ensure to vent the system before installation or removal toprevent equipment damage or serious injury. Pressure test the system with water before initial start-up.

Please Ensure Full Pipe
Install the TK Series in a horizontal or vertical direction with sufficient straight pipe length to avoid turbulent flow that may affect readings. Follow the minimum pipe diameter requirements upstream and downstream as specified.
Filtering Device Recommendation
Install a Bag Filter or Y Strainer upstream to protect the paddle wheel from damage by solids or fibers. Ensure the particle size does not exceed 10% and avoid flushing the pipe withcompressed air after installation as it may damage the ceramic shaft.

Safety Information

Depressurize and vent 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/or service

DO NOT alter product construction

Please ensure that the Instruments are not to be subject to water hammer or pressure spikes! Always Pressure Test System with H2O Before 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 affect readings.

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.

New ShearPro® Design

Contoured Flow Proﬁle

Reduced Turbulence = Increased Longevity? 78% Less Drag than Old Flat Paddle Design*
