It is used to alert you to potential physical injury hazards. Obey all safety messages that follow this symbol to avoid possible injury or death. Daniel designs, manufactures and tests products to function within specific conditions.
Because these products are sophisticated technical instruments, it is important that the owner and operation personnel strictly adhere both to the information printed on the product and to all instructions provided in this manual prior to installation, operation, and maintenance.
If this is not the correct documentation, contact Daniel at Figure Flange stabilizers A. The transducers are not exposed to the process pressure and can remain installed in the meter. Page Routine Maintenance Section 1: Routine maintenance Maintenance and Troubleshooting Manual December Rev F Routine Maintenance Routine maintenance operations requires adherence to all applicable regulations and laws and safety training for personnel to perform the maintenance operations.
Trending the logs indicates changes from the original installation of the meter over time. Some alarms do not require an acknowledge and will clear automatically when the alarm condition goes away.

Page 34 Section 2: Troubleshooting Maintenance and Troubleshooting Manual December Rev F The following details the information displayed in this dialog box. If reverse Meter Flow Properties Table flow is detected, check for valve leaks.
Attempting to do so may release pressurized fluid, resulting in serious injury or equipment damage. Failure to do so could allow the meter to roll, resulting in serious injury or equipment damage. Meter maintenance Page Transducer Field Removal And Installation Maintenance and Troubleshooting Manual Section 3: Meter maintenance Rev F December Transducer field removal and installation The liquid ultrasonic meter transducers are a spring-loaded assembly with the piezoelectric element at one end and the electrical connection at the other end.
Daniel Series Ultrasonic Flow Meters are supplied with transducers which are extractable while the line is pressurized. Coupling nut C. Transducer retainer D. Transducer E. Transducer housing locking ring F. Wear appropriate personal protective equipment when working on the meter.
Failure to do so may cause serious injury. Place the new transducer into the transducer housing. Rotate the transducer so that the alignment notch on the back of the transducer fits over the indexing pin on the back of the transducer housing. Page Transducer Housing Removal And Installation Section 3: Meter maintenance Reference, Installation and Operation Manual December Rev F Transducer housing removal and installation Daniel Series Ultrasonic Flow Meters utilize transducer housings that contain the transducer and act as the pressure barrier between the transducers and the fluid.
Under normal maintenance such as transducer replacement, the transducer housings do not need to be removed. If fluid begins to leak from the transducer housing, immediately reinstall it. Failure to do so may cause serious injury or equipment damage. Page 60 Section 3: Meter maintenance Reference, Installation and Operation Manual December Rev F Before removing the transducer housing s , slowly vent all line pressure on the meter to atmosphere pressure and drain the meter of fluid.

Remove the transducer s security seals. See Warnings on Pages 39 and 40 of this document.
Ensure the transducer housing threads are properly aligned avoid cross-threading the housing with the meter body, then use a wrench on the hex bolt of the housing and slowly screw in a clockwise direction.
Page Figure Transducer Installation Section 3: Meter maintenance Reference, Installation and Operation Manual December Rev F Slide the locking ring onto the transducer housing in an orientation so that the locking ring bolt can be installed through the slot of the locking ring and into the threaded hole in the meter body. This is necessary anytime transducers or housings have to be replaced for a chord or if the meter has performed a cold start.
Page Figure Transducer Swap Out Wizard - Select Components Page Section 3: Meter maintenance Reference, Installation and Operation Manual December Rev F Chord select components page When transducer pairs are replaced or the meter has performed a cold start, the corresponding meter calibration parameters must be updated for accurate operation. Select the chord parameters which have changed see Figure example: Transducers and Housings are After the values are entered, click the Write to Meter button to apply the changes.
The lengths of t he transducer housings are etched on on the individual components. Page Transducer Cable Removal And Installation Maintenance and Troubleshooting Manual Section 3: Meter maintenance Rev F December Transducer cable removal and installation Daniel Series Ultrasonic Flow Meters have blue transducer cables and a transducer cable nut that threads directly into the back of the transducer housing. The cables use plastic glands that come with the meter.
Base enclosure transducer cable glands B. Cable ties two locations for large size meters C. Make sure the enclosure is stable and does not roll. When terminating the connector wires, ensure that the contacts clamp on the bare wires and not on the wire insulation.
Attach one desiccant pack to the underside of the Base Enclosure cover.
Choose holes that minimize counterclockwise rotation of the end cap when the security wire is taut maximum wire diameter. Figure Base Enclosure security seals A.

Observe all warning labels on the meter before starting this procedure. Refer to Figure for the tools required to complete this procedure. Disconnect security seals on the Transmitter Electronics Enclosure see Figure , loosen the end cap security latches using a 3 mm Allen wrench If required, install the security seal wire into and through one of the two holes in the end cap.
