L characteristics and advantages

L four channel design ensures accuracy, stability and repeatability, and saves operation cost.

L has been running steadily for a long time, which greatly reduces the maintenance cost.

L high range ratio > 100:1, small diameter pipeline can be selected, and overall investment is lower.

The L random CUI (user - Ultrasonic software) provides a Windows - based interface that is easy to operate, reduces the time for new instrument debugging, and simplifies the routine maintenance process.

The L Mark III electronic unit provides rapid sampling and data output, an extensible electronic platform, easy to use, and archived data records * (options) to implement the diagnosis, alarm, and reading of records per hour and every day.

The casting structure of L machine is not sensitive to pressure change, so it will not affect the measurement uncertainty.

L sensor is easy to take out and easy to check

Instrument performance

The calibration accuracy of L is 0.1% (relative to laboratory).

The absolute accuracy of L is 0.3% (including laboratory uncertainty).

When the L velocity is 1.5~30 M / s, the repeatability is + 0.05%

L flow rate can reach 30 m / sec, and the maximum can reach and exceed 38.1 M / sec.

L ultrasonic working principle:

The SeniorSonic advanced ultrasonic gas flowmeter is used to measure the transmission time of ultrasonic pulses passing through gas in 4 parallel measuring channels. Daniel carefully selected the location of four measurement channels to optimize the accuracy of measurement. Each measurement channel has 2 ultrasonic sensors, alternately as the transmitting and receiving device of the ultrasonic signal, and accurately measuring the transmission time of ultrasonic wave in the current and countercurrent.

The difference between ultrasonic transmission time and downstream flow velocity is proportional to the velocity of natural gas.
