Tera ulang is the periodic legal re-verification of a measuring instrument by an authorised government officer, after which the instrument carries a valid verification mark. The current rule is Peraturan Menteri Perdagangan (Permendag) No. 24 of 2024 on tera and tera ulang of measuring, volume and weighing instruments and legal metrology accessories. It was enacted on 4 October 2024, promulgated and in force on 10 October 2024, and published in Berita Negara 2024 No. 669.
For fuel terminals and plants, two parts matter most: the annex that lists which instruments need tera ulang and how often, and the articles that say when re-verification is due early and who carries it out.
Intervals that matter for terminals
| Criterion | Tera ulang interval | Where you meet it |
|---|---|---|
| Electronic weighbridge | 1 year | Truck weighing at gates |
| Mechanical weighbridge | 1 year | Older weighing stations |
| Weighing in motion | 1 year | Vehicles weighed while moving |
| Automatic level gauge (radar, servo, float and others) | 2 years | ATGs on storage tanks |
| Depth tape and UTI | 1 year | Manual dipping |
| Fuel tank truck compartment | 2 years | Delivery trucks |
| Fixed vertical cylindrical tank | 6 years | Tank farm (insulated tanks: SKHP can be extended every 2 years) |
| Fixed spherical tank | 12 years | LPG storage |
When tera ulang is due early
Article 5(2) does not wait for the calendar. Tera ulang is required whenever one of four conditions applies, so a repair on a gauge or a weighbridge load cell can trigger it as surely as an expired mark.
The validity mark has expired
The verification mark is damaged or the seal wire is broken
A repair or change may affect the reading
The reading deviates from the technical requirements
Who carries it out
Article 3 classes instruments used in oil and gas exploitation, processing and transport, and in power generation and transmission, as needing special handling. Under Article 4 those go to the ministry's technical unit (UPT); other instruments are handled by the regional legal metrology unit (UML). Article 6 allows tera ulang at the unit, a laboratory, the site of a fixed installation, a re-verification session or the place of use, with the owner providing standards, test material, support equipment, helpers and a workspace.
Article 18 lets owners apply for exemption in set cases, for example tank truck, barge or ship tanks used only as transport. Article 44 gave officers appointed under the 2014 rule two years from 4 October 2024 to keep working before re-appointment, a window that has now closed.

Common questions
Does a weighbridge need tera ulang every year?
Yes. Annex I of Permendag 24/2024 sets a one-year tera ulang interval for both electronic and mechanical weighbridges.
How often must a radar or servo tank gauge be re-verified?
Every two years. The same interval applies to capacitance, ultrasonic, float and electromagnetic automatic level gauges.
How often is a storage tank re-verified under Permendag 24/2024?
Six years for fixed vertical cylindrical tanks for petroleum and related products, and twelve years for spherical tanks. For insulated tanks, the SKHP can be extended every two years.
Who performs tera ulang on oil and gas instruments?
The ministry technical unit (UPT), because Article 3 classes oil and gas instruments as needing special handling. Other instruments go to the regional UML.
