1.1 Product Description
Operating Principle:
Liquid flows through the turbine housing causing an internal rotor to spin. As the rotor spins, an electrical
signal is generated in the pickup coil. This signal is converted into engineering units (liters, cubic meters,
gallons etc.) on the local display where is applicable. Optional accessory modules can be used to export the
signal to other equipment.
Upon receipt, examine your meter for visible damage. The turbine is a precision measuring instrument and
should be handled carefully. Remove the protective plugs and caps for a thorough inspection. If any items
are damaged or missing, contact SURE.
Make sure the turbine flow model meets your specific needs. For your future reference, it might be useful
to record this information on nameplate in the manual in case it becomes unreadable on the turbine. Refer
to the nameplate for your customized product’s specification.
