The meter housing is supplied as a sealed unit. Therefore, customer field
repairs to these meters are not recommended. In the event of a malfunc-
tion, repairs should only be performed by a factory field service engineer,
or the complete meter returned to the manufacturer for service (shipping
Equipment powered by an ac line voltage presents a potential electric
shock hazard. Servicing of the flowmeter or signal converter should
only be attempted by a qualified electronics technician.
1. If improper meter operation is suspected, proceed as follows:
a) Remove the access cover from the meter junction box.
b) Inspect for evidence of water entry in the junction box.
If water is present, de-energize system at power source. Inspect conduit seals and cover gaskets for
possible source of water entry. Replace the seals and/or gasket as required. Allow interior of junction
box and converter housing to dry completely before restoring system power.
2. Since signal wiring and operating procedures are dependent upon the type of converter and the
mounting option selected, the user should refer to the instruction bulletin supplied with the signal
converter for system troubleshooting procedures. A static performance test for the meter mounted
components is discussed in Section 6.3.
3. Possible causes of erroneous flow rate indication are:
• incorrect grounding
• excessive noise due to a heavy slurry process
or a non-homogeneous process
• loose or intermittent wiring
• non-full or empty meter pipe
• excess air entrained in process liquid
• fluid conductivity below minimum specifications
4. The customer connection box mounted on the meter Primary contains an assembly of two printed
circuit boards. The upper board contains the terminal blocks for the customer connections as well as
a terminal strip with a jumper block labeled J1 (shown in FIGURE 3-2). The proper position for this
jumper in the 10DS3111E is between the center terminal and the lower terminal marked 16A as
shown in the figure below.
