First technology qualification certificate for fiscal metering
Emerson
’s Daniel 3415 and 3416 Dual-Configuration Gas Ultrasonic
Meters have received the industry’s first Technology Qualification
(TQ) fromDNV GL for fiscal gas meters, a risk-based assessment that
evaluates meter performance in real-life operational environments
to ensure the technology meets the highest fiscal measurement
standards.TheTQ verifies the meter’s ability to meet the industry’s
fiscal and contractual requirements when operating under field
conditions where dust, liquids, build-up, drift and pulsations are
common. It also authenticates the ability of the meter’s advanced
diagnostics to detect and compensate for process disturbances
and provide early warning of fouling to ensure greater meter in-
tegrity and measurement accuracy. Furthermore, theTQ confirms
the robustness and reliability of the new Daniel Ultrasonic Meters
in minimising financial risk and provides evidence to support ex-
tending calibration intervals to reduce operating costs. “Current
international gas measurement standards for fiscal flow meters
focus only on the design and installation of the meters and don’t
cover meter performance under field conditions,” said DNV GL’s oil
and gas senior vice president, Liv Hovem.
The Daniel Dual-Configuration 3415 and 3416 Gas Ultrasonic Me-
ters, which are already certified to the stringent OIML R137 1&2
Accuracy Class 0.5, are the only ultrasonic meters on the market
today that have undergone
DNV GL’s rigorous field testing
and demonstrated field robust-
ness. The DNV GL assessment
process is built upon scientific
research and is recognised by
regulators, insurers, and major
clients throughout the world.

Valve feedback systems for quarter-turn actuators
Available from
ifm electronic
, this unit contains two inductive sensors in a potted and sturdy housing with
protection rating IP 67. It signals two end positions. It is equipped with a solenoid connection replacing the
additional cable to the solenoid valve.The actuator interface is optionally equippedwith a standardisedM20 x
1 gland.The spacious terminal chamber allows quick and easywiring. Since the terminal block can be removed,
no new wiring is required if the sensor is replaced. A UL approval for this product is currently in progress.
