Owner manual

QUICKSTART OPERATING INSTRUCTIONS
This manual contains detailed operating instructions for all aspects of the flow metering instrument. The following condensed
instructions assist the operator in getting the instrument running as quickly as possible. This pertains to basic operation
only. Refer to the appropriate section in the manual for complete details on specific instrument features or if the installer is
unfamiliar with this type of instrument.
OTE:N The following steps require information supplied by the meter itself so it will be necessary to supply power to the
unit, at least temporarily, to obtain setup information.
Transducer Location
1. In general, select a mounting location on the piping system with a minimum of ten pipe diameters (10 × the pipe inside
diameter) of straight pipe upstream and ve straight diameters downstream. See Table 1 for additional congurations.
2. If the application requires DTTR, DTTN, DTTL or DTTH transducers select a mounting method for the transducers based on
pipe size and liquid characteristics. See Table 2. Figure 1 illustrates the three valid transducer congurations.
OTE:N All DTTS and DTTC transducers use V–Mount configuration.
3. Enter the following data into the transmitter via the integral keypad or the software utility:
1 Transducer mounting method 7 Pipe liner thickness
2 Pipe O.D. (Outside Diameter) 8 Pipe liner material
3 Pipe wall thickness 9 Fluid type
4 Pipe material 10 Fluid sound speed*
5 Pipe sound speed* 11 Fluid viscosity*
6 Pipe relative roughness* 12 Fluid specific gravity*
OTE:N * Nominal values for these parameters are included within the flow meter operating system. The nominal values may
be used as they appear or may be modified if the exact system values are known.

Electrical Connections
Transducer/Power Connections
1. Route the transducer cables from the transducer mounting location back to the ow meter enclosure. Connect the
transducer wires to the terminal block in the ow meter enclosure.
2. Verify that power supply is correct for the meters power option.
a. Line voltage AC units require 95…264V AC, 47…63 Hz @ 17 VA maximum.
b. Low voltage AC units require 20…28V AC, 47…63 Hz @ 0.35 VA maximum.
c. DC units require 10…28V DC @ 5 Watts maximum.
4. Connect power to the ow meter.
