LPM-zD
LPM-zD Ultrasonic Gas Flowmeter
- True zero-D installation
No upstream or downstream straight pipe lengths required, enabling installation in compact and disturbed pipeline layouts. - Custody transfer accuracy
Approved according to MID 2014/32/EU Class 1.0 and OIML R137 Class 1.0, suitable for regulated billing and allocation metering. - Patented ultrasonic technology
Broadband Continuous Wave transit-time measurement ensures excellent stability and accuracy across the full operating range. - Maintenance-free operation
No moving parts and rugged all-metal transducers result in minimal maintenance over the meter lifetime. - Fully intrinsically safe Certified for hazardous area use, allowing safe access to the display, keypad, and battery replacement without de-classification.
- Hydrogen-ready
Suitable for natural gas applications with up to 40% hydrogen blending, supporting future gas network transitions.
The LPM-zD offers the accuracy of high-end ultrasonic meters at the cost level of single-path solutions, while eliminating installation constraints associated with traditional flowmeters. Its zero-D capability, intrinsic safety, and hydrogen readiness make it an ideal choice for both current and future gas distribution networks. Backed by Transus Instruments’ expertise in ultrasonic flow measurement, the LPM-zD delivers long-term confidence for regulated gas metering applications.
- Actual and converted volume measurement Optional integrated pressure and temperature sensors enable on-board volume conversion.
- Industry-standard communication RS485 Modbus RTU for seamless integration into SCADA and telemetry systems.
- Extensive diagnostics Flow data and diagnostic information are accessible via the local LCD/keypad or Transus TIM® software.
- Flexible power options External 9–28 VDC supply or optional integrated battery pack for up to five years of operation.
