equipment and the environment.
• The LFC Types 8718 and 8719 are designed for controlling the flow-rate of clean and low-viscosity liquids.
• The LFM Types 8708 and 8709 are used exclusively for measuring the flow-rate of clean and low-viscosity liquids.
• Only the fluids stated on the rating plate and on the calibration protocol may be used for operation.
• If used outdoors, the device must be protected from the elements. Protect against humidity and direct
sunlight and observe the permitted ambient temperature.
• During use observe the authorized data and operating conditions specified in the contract documents and
