Product Usage Instructions
Safety Information
- 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.
Pressurized System Warning
The sensor may be under pressure. Vent the system prior to installation or removal to avoid equipment damage and serious injury.
Pressurize System Warning
Ensure full pipe installation with a minimum of 10x pipe diameters upstream and 3x pipe diameters downstream to avoid turbulence affecting readings. Use a Bag Filter or Y Strainer Filtering Device upstream to prevent damage to the paddle wheel. Do not flush the pipe with compressed air after installing the Flow Meter as it may damage the ceramic shaft and void the warranty.
Product Description
The TK Series in-line plastic paddle wheel flow meter is designed for accurate flow measurement in tough industrial applications. It features a contoured flow profile, reduced turbulence for increased longevity, and high wear resistance.
Features
- TK3B Sanitary Connection
- Zirconium Ceramic Rotor and Bushings for increased wear resistance
- True Union Design High Impact Enclosure with Bright LCD Display for easy monitoring
- Flanged Connection for secure installation
A: The operating pressure is 150 Psi (10 Bar) at ambient temperature with non-shock conditions.
Q: Can the flow meter be used with chemicals?
A: Yes, the flow meter is suitable for water or chemical liquid with a viscosity range of 0.5-20 centistokes.
Q: How should I prevent damage to the paddle wheel?
A: Install a Bag Filter or Y Strainer Filtering Device upstream to avoid damage from solids or fibers. Ensure proper pipe installation and avoid flushing the pipe with compressed air after installation.

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 turbulence that can effect readings.
Min 10x Pipe Diameters Upstream 3x Pipe Diameters Downstream
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.
