8719 / 8708, 8709 may be a hazard to people,
nearby equipment and the environment.
The LFC Types 8718 and 8719 are designed for con- •
trolling 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 report may be used for operation.
If used outdoors, the device must be protected from
•
the elements. Protect against humidity and direct sun-
light and observe the permitted ambient temperature.
During use observe the authorized data and operating
•
