Panametrics XMT1000 Liquid Flow Ultrasonic Transmitter

Overview

The Panametrics XMT1000 delivers dependable non-intrusive metering wherever plants need it; the Panametrics XMT1000 is a cost-effective liquid flow ultrasonic transmitter that builds on decades of Panametrics ultrasonic flow expertise and on the proven field performance of its XMT868i predecessor. The XMT1000 delivers state-of-the-art transit-time flow measurement in a rugged, locally-mounted or remote-mounted transmitter certified for use in hazardous (classified) locations, with improved accuracy of up to ±0.3% of reading, configurable analog and digital inputs and outputs, and support for one, two or three ultrasonic transducer paths. Because the meter has no moving parts, requires no filters or strainers, and introduces no pressure drop into the pipeline, it delivers long-term, drift-free flow measurement across hydrocarbon liquids, crude oil, lubricating oils, diesel fuel, LNG, water and wastewater, and general process chemicals.

Working closely with plant engineers in the region, Seven Star LLC proudly supplies the XMT1000 ultrasonic flow transmitter to process plants, utilities and industrial facilities across Oman and the wider GCC.

Measurement Principle

The Panametrics XMT1000 uses the transit-time ultrasonic flow measurement technique, in which two transducers mounted on or in the pipe act as both ultrasonic signal generators and receivers, maintaining continuous acoustic communication with each other. In operation, each transducer alternately transmits and receives a defined number of acoustic pulses, and the on-board digital signal processor precisely measures the time interval between transmission and reception in both the upstream and downstream directions. When the liquid in the pipe is static, the downstream and upstream transit times are equal; when the liquid flows, the downstream transit time becomes shorter than the upstream transit time, and the magnitude and sign of that difference is directly proportional to the velocity and direction of the flowing liquid.

Standard on every XMT1000 transmitter, the proprietary Automatic Tracking Window feature dynamically sweeps the receiver window whenever the sound speed of the fluid changes, ensuring the meter continues to lock onto a reliable ultrasonic signal even when fluid composition, temperature, or entrained solids and gas bubbles are variable. This ensures accurate, repeatable measurement without moving parts, without contamination risk to the process fluid, and without the periodic recalibration burden associated with mechanical flow metering technologies.

Engineering Design of the Panametrics XMT1000

The Panametrics XMT1000 is housed in a rugged, powder-coated aluminum or optional 316 stainless steel enclosure rated for hazardous area installation, weighing approximately 4.5 kg with a compact 213 mm x 163 mm x 149 mm footprint suitable for mounting directly at the process measurement point or remotely on a wall bracket. A 128 x 64 monochrome LCD display presents up to two configurable measurement parameters, and a built-in magnetic six-button lockable keypad allows technicians to safely program and verify diagnostics on the transmitter without opening the enclosure in a classified hazardous area, eliminating the cost and delay of a hot work permit.

The transmitter ships standard with RS485/Modbus connectivity, with optional HART 7.0 and Foundation Fieldbus FISCO communication for integration into existing plant control and asset management systems. Onboard data storage logs up to 10,000 flow data points across 26 parameters, and the meter can be configured with one, two or three measurement channels and matching numbers of ultrasonic transducer paths, letting engineers scale accuracy and redundancy to the criticality of the application, from a single clamp-on path on a utility line to a fully redundant multi-path configuration on a custody-adjacent transfer point.

Key Features

The XMT1000 is engineered for accuracy, flexibility and long-term reliability in demanding liquid flow applications. Key features include:

• Improved flow accuracy of up to ±0.3% of reading, achievable with a complete process-calibrated flow meter system.
• One, two or three-channel operation with matching multi-path ultrasonic transducer configurations for redundancy and accuracy.
• Automatic Tracking Window signal processing that maintains lock even as fluid sound speed changes.
• Four configurable analog or digital inputs and outputs for flexible integration with plant control systems.
• Hazardous area certification including US/Canada Class I Division 1 and ATEX/IECEx Ex d IIC T6.
• Magnetic six-button keypad for safe in-field programming without opening the enclosure.
• Onboard data logging of up to 10,000 flow data points across 26 parameters per point.
• Optional HART 7.0 and Foundation Fieldbus FISCO digital communication for control system integration.

Industrial Applications

The Panametrics XMT1000 is a familiar sight on plant piping across the region. The Panametrics XMT1000 is widely deployed across Oman’s oil and gas, water, and process industries wherever non-intrusive, maintenance-free liquid flow measurement is required. Upstream and midstream operators use the XMT1000 with wetted or clamp-on transducers to monitor crude oil, produced water and chemical injection flows without introducing pressure drop or moving parts into the pipeline, while refinery and petrochemical facilities rely on its hazardous-area certification to measure hydrocarbon and solvent flows directly within classified process areas. District cooling plants, RO desalination facilities and hospitality developments across the Sultanate also use the XMT1000 for chilled water and utility flow measurement where non-invasive installation minimizes shutdown time.

With fast quotation turnaround and technical support, Seven Star LLC distributes the XMT1000 to industrial and utility operators throughout Oman and the GCC, including facilities in the Sohar and Salalah economic zones where large-bore cooling water and process liquid lines benefit from clamp-on installation without cutting into an operating pipe. Our applications engineers assist clients in Muscat and beyond with transducer selection, path configuration and commissioning support, ensuring each XMT1000 installation delivers the accuracy the process requires from day one.
