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 ANYPERSON.

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.

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.

and to dispose of any product returned to Flowline where:

a. There is evidence of a potentially hazardous material present

with product.

30 days after dutifully requesting disposition of the product.

implied. EXCLUDED FROM THIS WARRANTY IS THE

About Ultrasonic Technology:

An ultrasonic sound wave is pulsed three times per second from the
base of the transducer. The sound wave reflects against the process
medium below and returns to the transducer. The microprocessor
based electronics measures the time of flight between the sound gen­eration and receipt, and translates this figure into the distance between
the transmitter and process medium below.
