Warranty, Terms, and Conditions

Proteus Industries warrants our flow products to be free from defects in materials and workmanship for five years from the date of shipment.


Proteus Industries warrants Proteus-manufactured flow products to be free from defects in materials and workmanship for a period of five (5) years from the date of shipment. Tofco instruments and other products distributed by Proteus are covered under the warranties of their respective manufacturers. Flow sensor calibration is warranted for one (1) year. Altering or removing the factory calibration label from a product, or the field replacement of parts, voids the calibration warranty.


Proteus warrants WeldSaver™ products to be free from defects in materials and workmanship for a period of two (2) years from the date of shipment. Equipment or parts that have been subject to abuse, misuse, accident, alteration or neglect are not covered by this warranty. Flow rate calibration is warranted for one (1) year. Defects caused by failure to perform periodic maintenance or the repair or replacement of blocked solenoid valves are not covered by this warranty.


Proteus’ obligation is limited to repair or replacement at Proteus’ option, and is contingent on written notification of the defect within 90 days of discovery. Repairs are warranted for one (1) year from the date of repair or the remainder of the original product warranty, whichever is longer.


Our warranty does not cover alterations made to our products. If a Customer requires components to be used that differ from the original Proteus specification then such components are subject to the warranty terms of the Customer specified manufacturer.

Our warranty coverage is restricted to the form of the product in which it is originally delivered to our customer. Failures due to a customer declining to approve changes recommended by Proteus are not covered for products shipped after the date on which the recommendation was made.


This warranty is exclusive and in lieu of all other expressed or implied warranties, including fitness for a particular purpose, except as made in writing by Proteus. Proteus shall not be liable for any defects attributable to the acts or omissions of others after shipment, nor for any consequential, incidental or contingent damages whatsoever.


Our flexible manufacturing process allows many standard products to be shipped on the next business day if your order and credit clearance are received by 1:00 PM Pacific Time. Products requiring calibration have a lead time of 3 to 10 working days depending on quantity and calibration requirements. Lead times for WeldSaver™ products are provided by individual quotation.


For blanket and period orders for standard and customized products, you specify your dock date and preferred shipping method, and we will make sure it arrives on time, every time.
