The Panametrics PanaFlow Z1G ultrasonic flowmeter is designed to measure the flow rate of virtually any gas, offering a unique combination of accuracy, range-ability, and reliability in a robust meter design. Employing ultrasonic time differential technology, the PanaFlow Z1G flowmeter has no moving parts and generates no flow obstruction or energy-robbing pressure drops. Virtually maintenance free, the Z1G will provide years of trouble-free operation with no adjustments, tuning or corrections.

The PanaFlow Z1G is a complete ultrasonic flow metering system specifically designed for the measurement of gases with high levels of impurities. Designed as a well-head meter for coal-seam methane extraction and bio-gas measurement, the Z1G is engineered to the highest levels of reliability and dependability. Designed with an all-cast body and high accuracy machined surfaces, the Z1G has no welds that can adversely impact flow dynamics, making possible high accuracy flow measurements, even at low flow conditions.

The Z1G employs ultra-high power transducers with enhanced sound isolation designed for conditions of extreme condensate and impurities, assuring continuous operation even under the harshest of process conditions. The meter body eliminates exposed wires that can catch, or fail due to extreme environmental conditions. Flow measurement range is 0.5 to 250 ft/s depending on pipe size, with ±1.5% accuracy and ±0.5% repeatability. The enclosure is NEMA Type 4X IP66, explosion-proof and weatherproof, with built-in magnetic, six-button keypad operation.
