Research findings
Filter-difference study
Against the 38-record Smart Grid Energy Metering Terminals Keyword Candidate Study, this 33-record cohort shares 32 records. Only 1 occur here and 6 only in the reference; the union contains 39. These are filter-membership differences, not company entries or exits.
| Company cohort | Directly linked pages | Share of public archive | Archive date |

An ID-deduplicated archive snapshot, not the whole market, current recognition or operating results.
Filter differences and comparison link
The largest recorded sub-industry participation gap is for Smart gas meters and metering terminals: 0/33 here versus 3/38 in the reference, an absolute difference of 7.9 percentage points. The cohorts have overlapping company IDs and are not independent samples.
| sub-industry | Focal count/base | Reference count/base | Participation gap (pp) |
|---|---|---|---|
| Smart gas meters and metering terminals | 0/33 | 3/38 | -7.9 |
| Smart electricity meters and energy-metering terminals | 19/33 | 19/38 | +7.6 |
| Construction-machinery instruments and smart power-distribution control | 2/33 | 1/38 | +3.4 |
| Instrumentation and testing equipment | 0/33 | 1/38 | -2.6 |
| Charging infrastructure | 0/33 | 1/38 | -2.6 |
Zero means no recorded label, not no business; multi-label cells overlap.

Recorded roles and delivery checks
Check traceability and conditions before comparing measurement data
The Smart electricity meters and energy-metering terminals label covers 19 records (57.6% of this cohort). This archive clue raises a verification question about Measurement data or instruments with defined objects and methods; it does not establish that these companies already deliver it.
