otherwise expressly provided herein, Daniel Measurement and Control, Inc. ("Daniel") warrants that the
firmware will execute the programming instructions provided by Daniel, and that the Goods
manufactured or Services provided by Daniel will be free from defects in materials or workmanship
under normal use and care until the expiration of the applicable warranty period. Goods are warranted
for twelve (12) months from the date of initial installation or eighteen (18) months from the date of
shipment by Daniel, whichever period expires first. Consumables and Services are warranted for a
period of 90 days from the date of shipment or completion of the Services. Products purchased by
Daniel from a third party for resale to Buyer ("Resale Products") shall carry only the warranty extended
by the original manufacturer. Buyer agrees that Daniel has no liability for Resale Products beyond
making a reasonable commercial effort to arrange for procurement and shipping of the Resale Products.
If Buyer discovers any warranty defects and notifies Daniel thereof in writing during the applicable
warranty period, Daniel shall, at its option, promptly correct any errors that are found by Daniel in the
firmware or Services, or repair or replace F.O.B. point of manufacture that portion of the Goods or
firmware found by Daniel to be defective, or refund the purchase price of the defective portion of the

IMPORTANT INSTRUCTIONS
• Read all instructions prior to installing, operating, and servicing this product.
• Follow all warnings, cautions, and instructions marked on and supplied with this product.
• Inspect the equipment packing case and if damage exists, notify your local carrier for
liability.
• Open the packing list and carefully remove equipment and spare or replacement parts
from the case. Inspect all equipment for damage and missing parts.
• If items are missing, contact your local Product Services Department representative or
the sales office. Provide the equipment serial number and sales order number to the
Product Services Department or sales representative.
All returned equipment or parts must have an RMA (Returned Materials Authorization)
form obtained from the Products Services Department. Complete the Customer Problem
Report or include a letter describing the problem and corrective action to be performed at
the factory.
Phone: 1 (713) 827-5033
• Physically attach the RMA, corrective action documentation, and a copy of the packing
list to the equipment and place inside the shipping case. An envelope with a copy of the
packing list may be attached to the outside of the shipping case. Send to the address
shown above.
• Install equipment as specified per the installation instructions and per applicable local and
national codes. All connections shall be made to proper electrical and pressure sources.
• Ensure that all equipment doors are closed and protective covers are in place, except
when maintenance is being performed by qualified persons, to prevent personal injury.
• Use of this product for any purpose other than its intended purpose may result in property
damage and/or serious injury or death.
• Before opening the flameproof enclosure in a flammable atmosphere, the electrical
circuits must be interrupted.
• Repairs must be performed using only authorized replacement parts as specified by the
manufacturer. Use of unauthorized parts can affect the product's performance and place
the safe operation of the product at risk.
• When installing or servicing ATEX certified units, the ATEX approval applies only to
equipment without cable glands. When mounting the flameproof enclosures in a
hazardous area, only flameproof cable glands certified to IEC 60079-1 must be used.

1.1 MANUAL OVERVIEW
The Daniel Ultrasonic Gas Flow Meter Mark III Electronics Reference,
Installation, and Operations Manual (P/N 3-9000-743) provides
descriptions and explanations of the Daniel Multipath SeniorSonic
Model 3400 and Model 3422, Single Path JuniorSonic
the Dual Path JuniorSonic
TM
- Model 3420.
TM
- Model 3410 and
The Daniel Ultrasonic Flow Meter was originally developed and tested by
British Gas. The unit was further developed by Daniel and features
hardware and electronics designed for easy use and minimum
maintenance. All parts and assemblies have been tested prior to
shipment. Daniel holds an exclusive license from British Gas, obtained in
1986, to manufacture and sell this product.
