Introduction
Webtec turbine flow meters provide a precision solution to the measurement of flow in hydraulic systems on test stands,
machine tools and other fixed or mobile applications. The flow meters can be installed anywhere in the hydraulic circuit
for production testing, commissioning, development testing and analysis of control systems. The compact design of
the flow meter allows them to be installed where space is limited. The LTR turbine flow meter with frequency output
provides a precision solution to the flow measurement. The CTR turbine flow meter has a built-in microcontroller that
conditions the signal from the flow meter to provide an accurate analogue output. This enables you to connect the flow
meter directly into your digital display, PLC or custom DAQ system without having to worry about complex calibration
factors or lookup tables. Four main versions are available offering 4 - 20 mA current loop, 0 - 5 V or 0 - 3 V (Sensor
Recognition) output.
The integral loading valve provides smooth progressive pressure control in both flow directions allowing components
such as cylinders or motors to be tested without re-plumbing the test connections.
The range of products can be divided into two families:
1. Standard CT/LT
2. CTR/LTR, a flow turbine with a built in load valve
This manual covers the CTR/LTR range of products.
Before first operating the equipment read the whole of these instructions. Safety may be impaired if they are not followed.
Webtec have been designing and manufacturing flow meters and hydraulics components for over 40 years. We operate
within a Quality Management System that complies with the requirements of BS EN ISO 9001 which is externally
audited and certificated each year. Beyond compliance to the standard, Webtec is committed to continually improving
in everything we do; with particular emphasis on understanding what matters to our customers and suppliers, and
designing our systems and work to meet their needs. We are always keen to hear from customers who may have special
requirements not covered by our standard ranges
