- Confirm chemical compatibility before use
- DO NOT exceed maximum temperature or pressure specifications
- ALWAYS wear safety goggles or face-shield during installation and/or service
- DO NOT alter product construction
Warning | Caution | Danger
- Indicates a potential hazard. Failure to follow all warnings may lead to equipment damage, injury, or death.
Note | Technical Notes
- Highlights additional information or detailed procedure.
Personal Protective Equipment (PPE)
- Always utilize the most appropriate PPE during the installation and service of Truflo® products.
Pressurized System Warning
A sensor may be under pressure. Take caution to vent the system before 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 the Test System with H2O Before the 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
- The sensor may be under pressure, take caution to vent the 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.
- Min 10x Pipe Diameters Upstream 3x Pipe Diameters Downstream (See Page 10)
- 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 the 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 an 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*
