Diaphragm Smart Meter
To Connect x To Spread" Microcomputer S Meter
This diaphragm-type smart meter is designed to create a variety of "To Connect x To Spread" worlds in anticipation of the IoT society. A built-in wireless communication terminal can be installed under the counter.
Features
Built-in LTE-M communication module
Additional Functions
Load survey and pressure value acquisition and retention functions have been added.
Weighing and Compactness
The weight has been reduced from approximately 2.3 kg*1 to approximately 2 kg, making it lighter and more compact, and further pursuing user-friendliness.
Time Reduction
The time required to confirm the return leakage has been significantly reduced from approx. 50 sec. in the previous version*1to approx. 17 sec.
The time required to check for flow-type small leaks has been significantly reduced from approx. 45 min. in the previous version*1 to approx. 15 min.
Clear meter status
The shutdown event is indicated in kanji characters, and the pressure value is also indicated numerically, making the meter status clearer.
*1：Compared with our microcomputer meter S (
™) for LP gas.
