Product Usage Instructions
Safety Information
Please follow these safety guidelines when using the In-Line
Paddle Wheel Flow Meter Sensor:
- 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.
Personal Protective Equipment (PPE)
Ensure you wear appropriate Personal Protective Equipment (PPE)
when handling the sensor due to potential pressurization. Vent the
system prior to installation or removal to avoid injury or
equipment damage.
Installation Guidelines
When installing the TK Series in-line plastic paddle wheel flow
meter:
- Ensure the sensor is not subject to water hammer or pressure
spikes. - Pressure test the system with water before initial
start-up. - Install the sensor with at least 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 by solids or fibers.
Frequently Asked Questions (FAQ)
Q: Can the sensor be installed horizontally or vertically?
A: Yes, the TK Series can be installed in a horizontal or
vertical direction. Ensure there is enough straight pipe length to
avoid turbulence that can affect readings.
Q: What is the maximum operating pressure of the sensor?
A: The sensor can operate at a maximum pressure of 150 Psi (10
Bar) at ambient temperature without shock.

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
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.
