Product Usage Instruction
Safety Information
Safety is paramount when using the In-Line Paddle Wheel Flow Meter Sensor. Please adhere to the following safety guidelines:
- De-pressurize and vent system prior to installation or removal.
- 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.
PPE and System Precautions
To ensure safe operation of the sensor, follow these precautions:
- Vent the system prior to installation or removal to prevent pressurized accidents.
- Avoid water hammer or pressure spikes by maintaining proper pressure levels.
- Maintain a full pipe for accurate readings; install in a horizontal or vertical direction with adequate straight pipe lengths.
- Minimize turbulent flow by ensuring at least 10x pipe diameters upstream and 3x pipe diameters downstream.
- Use a Bag Filter or Y Strainer upstream to protect the paddle wheel from damage by solids or fibers.
- Do not flush the pipe after installation with compressed air as it may damage the ceramic shaft.

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.
