PanaFlow™ XMT1000

Panametrics liquid flow ultrasonic transmitter
The XMT1000 is a new, cost-effective ultrasonic flowtransmitter that builds on Panametrics flow expertise and onyears of reliable performance from its XMT868i predecessor.
It offers state-of-the-art flow measurement capability in arugged, locally-mounted or remote-mounted transmitter
certified for use in hazardous areas. It brings a new level ofperformance with improved accuracy, configurable inputs
and outputs, and multiple ultrasonic transducer path options.

Non-intrusive, reliable, and accurate flowmeasurement

Liquid flow measurements for a wide rangeof applications• Crude oil

Its on-board digital signal processor (DSP) provides
proprietary digital signal coding and correlation detection
routines, automatic adjustment to changing fluid properties,
and dynamically-configured operating software to simplify
programming.

• Lubricating oil

The XMT1000 offers:• Diesel fuel oil• Improved accuracy of 0.3% of reading• Solvents• One, two or three-channel operation• Liquefied natural gas (LNG)• Four configurable inputs/outputs for analog or digitalcommunication• Hydrocarbon liquids• Water and wastewater• Distilled water• Hot/chilled water• Chemicals• Beverages

The PanaFlow XMT1000 comes from a long line of provenultrasonic flow meters from Panametrics. It shares all theadvantages of ultrasonic flow measurement, no moving
parts to wear, no filters or strainers, no maintenancerequirement, no pressure drop, and no drifting or required
periodic calibration.

• Suitability for a wide range of pipe sizes and materials• SIL configuration available

Improved programming capability
The XMT1000 introduces a magnetic six-button keypad toallow safe programming and diagnostics verification in yourhazardous (classified) location. There is no need to open thecase to use a PC to program, eliminating the cost and timeassociated with obtaining hot work permits, and there is noneed for an additional handheld programmer. Just touch theglass of the XMT1000 with the magnetic wand to change any
parameter setting.
If you prefer your PC interface, the PanaFlow XMT1000
comes standard with MODBUS RS485 connectivity, providing
full access to the meter’s diagnostics and programming
using PanaView Plus software. PanaView Plus also provides
continuous logging capability of up to 10,000 points with 26
parameters logged per point.

Multi-channel, multi-path options reduce costs
and improve performance
The XMT1000 may be configured as a one-channel, twochannel or three-channel meter for measurement flexibility.
It also offers one, two or three ultrasonic transducer paths.
A single path can provide cost effective flow measurement
while multiple paths improve flow measurement accuracy
and repeatability and add redundancy.

Automatically adjusts to changing
fluid properties
Standard in all PanaFlow XMT1000 transmitters, our unique
Automatic Tracking Window™ (ATW™) feature ensuresaccurate flow measurements even when fluid properties are
unknown or changing. ATW dynamically sweeps the receiverwindow whenever the sound speed of the fluid changes. Thispowerful feature lets you measure flow when the fluid soundspeed is unknown, or is changing.

PanaFlow XMT1000 flow transmitter uses
transit-time flow measurement techniqueDownstream wetted
transducer

Upstream wetted
transducer

The transit time flow measurement method utilizes twotransducers to serve as both ultrasonic signal generatorsand receivers. When mounted on a pipe, they are in
acoustic communication with each other. In operation,
each transducer functions as a transmitter, generating acertain number of acoustic pulses, and then as a receiver
for an identical number of pulses. The time interval between
transmission and reception of the ultrasonic signals is
measured in both directions. When the liquid in the pipe isnot flowing, the transit-time downstream equals the transittime upstream. When the liquid is flowing, the transit-time
downstream is less than the transit-time upstream.
The difference between the downstream and upstream
transit times is proportional to the velocity of the flowing
liquid, and its sign indicates the direction of flow.

Wetted transducers
The XMT1000 can be used with a variety of wetted systems
including the PanaFlow system. The PanaFlow system offers afully integrated flow meter solution that includes the XMT1000
electronics, flow cell, and transducers, which simplifies
installation.
The PanaFlow XMT1000 can be used with other PanaFlow
systems or may be configured as a custom meter solution
with wetted transducers to meet specific application needs.

Flow accuracy (velocity)

Up to ±0.3% of reading (achievable when supplied witha complete flow meter system and process calibration).
Accuracy depends on pipe size, installation and number ofmeasurement paths.
The accuracy statement assumes measurement of asingle phase homogeneous liquid with a fully developedsymmetrical flow profile passing through the meter.
Applications with piping arrangements that create an
asymmetrical flow profile may require extended piping
straight runs and/or flow conditioning for the meter toperform to this specification.
