Daniel® SeniorSonic™ and JuniorSonic™
Gas Flow Meters with Mark III™ Electronics
The Daniel® SeniorSonic™ Gas Flow Meter is designed
for natural gas custody transfer where high accuracy
and long-term, reliable performance is critical. It utilizes
Mark III Electronics, Customer Ultrasonic Interface (CUI)
software, and optional features for exceptional flow
measurement. This advanced 4-path chordal meter helps
customers reduce lost and unaccounted natural gas with
exceptional accuracy and linearity throughout the flow
range.
The Daniel® JuniorSonic™ Gas Flow Meter also utilizes
Mark III™ Electronics, the same Customer Ultrasonic
Interface (CUI) software, and supports the same optional
features as the SeniorSonic meter. Its bounce design was
developed for accurate flow measurement of non-custody
transfer applications such as production measurement,
gas storage, and wet gas applications.
Both meters measure transit times of ultrasonic pulses
passing through the gas. The difference in transit times
of the downstream directed pulses and the upstream
directed pulses is measured. The SeniorSonic flow meter
measures transit times on four, carefully chosen, parallel
chords. The JuniorSonic flow meter measures flow by
bouncing a signal across the meter in one and two path
meter designs. Each path is comprised of ultrasonic
transducers that act alternately as transmitter and
receiver. Upstream and downstream measurement times
are accurately measured, and the difference is directly
proportional to the velocity and volume of flowing natural
gas.
Mark III Electronics provides fast sampling and output,
an expandable electronics platform, ease-of-use, and
an optional archive data log* which enables the reading
of audit, alarm, system, hourly, and daily
log information
The addition of the Series 100 Options Board provides
a direct input of pressure, temperature, and gas
composition into the meter which allows the meter
to act as a redundant flow computer; it calculates
corrected volume rates, mass rates, energy rates, and
AGA 10 speed of sound*
Machined, cast body construction for the SeniorSonic
is virtually insensitive to measurement uncertainty
caused by changes in pressure
Extractable transducers for ease of inspection
*Optional (requires software key)
Features and Benefits
SeniorSonic four-path chordal design allows accuracy,
stability, redundancy, and operational cost savings
JuniorSonic one-path or two-path, single bounce
designs provide a lower cost solution for production
measurement, gas storage, and wet gas applications
where fiscal measurement is not required, the twopath design provides redundancy for more critical
applications
Excellent long-term performance reduces
maintenance costs
High rangeability of >100:1 means fewer meter runs,
smaller line sizes, and lower capital costs
Customer Ultrasonic Interface (CUI) software offers
easy-to-use and learn Windows® based meter
interface, reduces time to commission a new meter,
and simplifies routine maintenance

Calculating meter capacity:
To calculate a volume rate for a given velocity, first find the capacity in this table for the meter size and operating pressure.
Next, multiply the capacity by the ratio of the desired velocity divided by 100 ft/s to obtain the desired volume rate.
Example: Determine the hourly flow rate at 70 ft/s for an 8-inch meter operating at 800 psig.
Flow Rate = 7635 MSCFH
Velocity = 70 ft/s
Answer = 7635 MSCFH x 70 ft/s = 5344 MSCFH
100 ft/s

Selection of Meter Size:
These tables can be used to determine the flow range at reference conditions for all meter sizes. All calculations are based on
Schedule 40 bore, 15° C and typical gas composition. These values are intended to be a guide in sizing. Contact Daniel engineering
for assistance with specific applications.

Calculating meter capacity:
To calculate a volume rate for a given velocity, first find the capacity in this table for the meter size and operating pressure.
Next, multiply the capacity by the ratio of the desired velocity divided by 30 m/s to obtain the desired volume rate.
Example: Determine the hourly flow rate at 21 m/s for an 8 inch meter operating at 4500 kPag.
Flow Rate = 171.6 MSCMH
Velocity = 21 m/s
Answer = 171.6 MSCMH x 21 m/s = 120.12 MSCMH
30 m/s

!
Do not operate this instrument in excess
of the specifications listed. Failure to
heed this warning could result in serious
injury and/or damage to the equipment.
*Note: these are minimum lengths. Many users specify 10 D + Flow Conditioner + 10 D for upstream in uni-directional designs and the same
for bi-directional designs.
