Secure Meters — Saral single-phase direct-connected meter (net-metering use)
A compact, IP54 single-phase meter that Secure says suits net metering — to IS 13779 and IS 15959 rather than the IS 16444 smart-meter standard.
Reviewed 6 October 2026
Secure’s Saral is a small single-phase, two-wire, direct-connected “intelligent credit meter” for domestic and small commercial use, and the maker’s page includes net metering among its applications. It comes in 5–30 A, 10–60 A and 10–100 A versions, 230/240 V, accuracy class 1.0, 50/60 Hz, with meter constants of 6,400, 3,200 or 1,280 imp/kWh.
The standards listed are IS 13779, IEC 62052-11, IEC 62053-21 and IS 15959 (the Indian data-exchange standard). Not listed is IS 16444, the smart-meter standard that the Genus and L&T meters we reviewed claim — Saral is described as an intelligent meter, not a full smart meter with a communications module and remote relay on the page we read.
Hardware claims: IP54 engineering-plastic enclosure, 10 kV surge withstand, operation from −20 °C to +60 °C (storage −25 °C to +70 °C), up to 95% non-condensing humidity, about 0.3 kg and 95 × 130 × 60 mm. Features include anti-tamper functions, current and temperature profiling to help spot loose connections and burning attempts, reading in the absence of mains, peak/off-peak tariffs and optional Bluetooth Low Energy walk-by reading.
For Installers & Engineers
Deeper technical detail beyond the homeowner-facing summary above.
The page says “including net metering” but does not explain how the meter registers export (a second register, or a bi-directional configuration). A DISCOM approving a net meter will have its own requirements on that, so the claim on a product page is not approval.
IP54 and −20 °C to +60 °C is a somewhat wider environmental envelope than the IP51, −10 °C to +55 °C stated for the Genus and L&T smart meters, which suits a hot meter box on an Indian roof or wall.
The current/temperature profiling and tamper features are aimed at the utility’s revenue protection: a meter that detects a loose terminal helps prevent the burn-outs that cause outages and fires at the meter box.
We found a distributor listing that quotes a five-year warranty and “UP approved” status for this meter. Secure’s own page states neither, so we treat both as unverified; ask the supplier for the approval letter.
The Scorecard
How we scoreStandards & Safety Compliance
Indian and IEC metering standards are listed and net-metering use is claimed, but there is no IS 16444 listing, DISCOM approval or explanation of export measurement.
Build Quality & Durability
IP54, 10 kV surge withstand and a −20 °C to +60 °C range are better than the other meters we reviewed.
Fit & Ease of Use
Compact, simple and has useful installation-fault profiling; limited communications on the page we read.
Documentation, Warranty & Support
A clean spec table from an established maker, but no warranty, approval list or datasheet date on the page.
Value for Money
Not assessed — DISCOMs normally supply or specify meters and we have not sourced an authoritative price.
Strengths
- IS 13779, IEC 62052-11 and IEC 62053-21 listed; accuracy class 1.0
- Net-metering use stated by the maker; three current versions up to 100 A
- IP54, 10 kV surge withstand and a −20 °C to +60 °C operating range
- Current and temperature profiling and anti-tamper features; optional BLE walk-by reading
Watch-outs
- The page does not say how export is registered, and it names no DISCOM approval
- Not listed as an IS 16444 smart meter; no remote-relay or cellular communication on the page we read
- No warranty or BIS registration is stated by Secure on this page; reseller claims are unverified
- Meters for net metering are normally specified or supplied by the DISCOM, not chosen by the owner

Our Verdict
A sturdy, simple single-phase meter that the maker positions for net metering, but the page proves less than it implies: no export-register explanation, no DISCOM approval, no warranty. Treat it as a candidate and get the approval in writing from your DISCOM.
Frequently Asked Questions
Is the Secure Saral a net meter?
The maker lists net metering among its applications, but the product page does not explain how export energy is registered or name any DISCOM approval. Confirm the exact variant with your DISCOM.
Is the Saral an IS 16444 smart meter?
The page lists IS 13779, IEC 62052-11, IEC 62053-21 and IS 15959 but not IS 16444, and describes an intelligent credit meter without a built-in cellular modem.
What current rating does the Saral come in?
Three versions are listed: 5–30 A, 10–60 A and 10–100 A, at 230/240 V single-phase.
