Product Details

Product Description:

The SWP-LCD-NLT (Intelligent) natural gas flow display and accumulation control instrument is suitable for online measurement of natural gas flow rate. It compensates and calculates the natural gas flow rate in the pipeline to automatically convert it into the natural gas volume flow rate and accumulation amount under industrial standard conditions.

1、 Instrument features

1. Simultaneously display multiple parameters of the natural gas flow measurement system (such as time, differential pressure, pressure, temperature, flow rate, cumulative quantity, etc.), and can also display FZ, FG, etc. according to user requirements, which is more conducive to monitoring production process parameters.

2. Can connect 3 tested signals, meeting the requirements of temperature compensation, pressure compensation, and temperature pressure full compensation integration.

3. The newly added power outage recording function can record the real-time time, number of power outages, and cumulative power outage time during the operation of the instrument, to prevent deviation in cumulative values caused by human or accidental power outages.
