GE Sensing XMT1000 Specifications

PanaFlow™ XMT1000

Panametrics Liquid Flow Ultrasonic Transmitter

The XMT1000 is a new, cost-eective ultrasonic ow transmitter that builds on Panametrics ow expertise

and on years of reliable performance from its XMT868i

predecessor. It oers state-of-the-art ow measurement

capability in a rugged, locally-mounted or remote-

mounted transmitter certied for use in hazardous areas. It brings a new level of performance with improved accuracy, congurable inputs and outputs, and multiple ultrasonic transducer path options.

Liquid Flow Measurements for a Wide Range of Applications

• Hydrocarbon liquids • Water & wastewater

• Crude oil • Distilled water

• Lubricating oil • Hot/chilled water

• Diesel fuel oil • Chemicals

• Solvents • Beverages

• Liquied natural gas (LNG)

Non-Intrusive, Reliable, and Accurate Flow Measurement

The PanaFlow XMT1000 comes from a long line of

proven ultrasonic ow meters from Panametrics. It shares all the advantages of ultrasonic ow measurment: no moving parts to wear, no lters

or strainers, no maintenance requirement, no pressure drop, and no drifting or required periodic

calibration.

Its on-board digital signal processor (DSP) provides

proprietary digital signal coding and correlation detection routines, automatic adjustment to

changing uid properties, and dynamicallycongured operating software to simplify programming.

The XMT1000 oers:

• Improved accuracy of 0.3% of reading

• One, two or three-channel operation

• Four congurable inputs/outputs for analog or digital communication

• Suitability for a wide range of pipe sizes and materials

Improved Programming Capability

PanaFlow XMT1000 Flow

The XMT1000 introduces a magnetic six-button keypad to allow safe programming and diagnostics verication in your hazardous (classied) location. There is no need

to open the case to use a PC to program, eliminating

the cost and time associated with obtaining hot work

permits, and there is no need for an additional handheld

programmer. Just touch the glass 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 Vitality™ software. Vitality 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 congured as a one-channel,

two-channel or three-channel meter for measurement

exibility. It also oers one, two or three ultrasonic transducer paths. A single path can provide cost eective ow measurement while multiple paths improve ow 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 ensures accurate ow measurements even when uid properties are unknown or changing. ATW dynamically

sweeps the receiver window whenever the sound speed

of the uid changes. This powerful feature lets you measure ow when the uid sound speed is unknown, or is changing.

Transmitter Uses Transit-Time Flow Measurement Technique

Downstream Wetted Transducer

Upstream Wetted Transducer

The transit time ow measurement method utilizes two

transducers to serve as both ultrasonic signal generators

and receivers. When mounted on a pipe, they are in acoustic communication with each other. In operation,

each transducer functions as a transmitter, generating a certain 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 is not owing, the transit-time downstream equals the transit-time upstream. When the liquid is owing, the transit-time downstream is less than the transit-time upstream.

The dierence between the downstream and upstream transit times is proportional to the velocity of the owing liquid, and its sign indicates the direction of ow.

Wetted Transducers

The XMT1000 can be used with a variety of wetted

systems including the PanaFlow system. The PanaFlow system oers a fully integrated ow meter solution that includes the XMT1000 electronics, ow cell, and transducers, which simplies installation.

The PanaFlow XMT1000 can be used with other

PanaFlow systems or may be congured as a custom meter solution with wetted transducers to meet specic application needs.
