WARRANTY

Flowline warrants to the original purchaser of its products that such prod­ucts will be free from defects in material and workmanship under nor­mal use and service for a period which is equal to the shorter of one year
from the date of purchase of such products or two years from the date of
manufacture of such products.

This warranty covers only those components of the products which are
non-moving and not subject to normal wear. Moreover, products which
are modified or altered, and electrical cables which are cut to length
during installation are not covered by this warranty.

Flowline’s obligation under this warranty is solely and exclusively lim­ited to the repair or replacement, at Flowline’s option, of the products
(or components thereof) which Flowline’s examination proves to its sat­isfaction to be defective. FLOWLINE SHALL HAVE NO OBLIGA­TION FOR CONSEQUENTIAL DAMAGES TO PERSONAL OR
REAL PROPERTY, OR FOR INJURY TO ANY PERSON.

This warranty does not apply to products which have been subject to
electrical or chemical damage due to improper use, accident, negligence,
abuse or misuse. Abuse shall be assumed when indicated by electrical
damage to relays, reed switches or other components. The warranty does
not apply to products which are damaged during shipment back to
Flowline’s factory or designated service center or are returned without
the original casing on the products. Moreover, this warranty becomes
immediately null and void if anyone other than service personnel autho­rized by Flowline attempts to repair the defective products.

Part # LP900001 8/98

Products which are thought to be defective must be shipped prepaid and
insured to Flowline’s factory or a designated service center (the identity
and address of which will be provided upon request) within 30 days of
the discovery of the defect. Such defective products must be accompa­nied by proof of the date of purchase.

THERE ARE NO WARRANTIES WHICH EXTEND BEYOND THE
DESCRIPTION ON THE FACE OF THIS WARRANTY. This warranty
and the obligations and liabilities of Flowline under it are exclusive and
instead of, and the original purchaser hereby waives, all other remedies,
warranties, guarantees or liabilities, express or implied. EXCLUDED
FROM THIS WARRANTY IS THE IMPLIED WARRANTY OF FIT­NESS OF THE PRODUCTS FOR A PARTICULAR PURPOSE OR USE
AND THE IMPLIED WARRANTY OF MERCHANT ABILITY OF
THE PRODUCTS.

This warranty may not be extended, altered or varied except by a written
instrument signed by a duly-authorized officer of Flowline, Inc.

If FLOWLINE level transmitters or switches are used for process control
where failure of the transmitter or switch could result in personal injury
or property damage, an independent means such as a redundant FLOW­LINE point level switch should be used. Where FLOWLINE level trans­mitters or switches are used as a part of a pressure vessel or pipe, care
should be taken to independently protect against personal injury or prop­erty damage should the FLOWLINE sensor fail or be mishandled. Con­tact FLOWLINE or your local distributor for additional information.
