MINING
Mining is our largest industry. We supply and service the process instrumentation used across the full mining value chain — from crushing and grinding circuits to flotation, leaching, thickeners, and tailings.
Our team has deep experience with gamma and level gauges for slurry pipelines, autoclaves, and thickener beds. We coordinate the full lifecycle of gamma sources in Lao PDR: import permits, transport, installation, periodic leak testing, and end-of-life return to the manufacturer.
We supply flow, level, pressure, temperature, pH, and analytical measurement for mineral processing plants. Our engineers have worked on gold, copper, and bauxite projects across Lao PDR and the region.
Why mining operators choose nValid:
-
Authorized Endress+Hauser representative in Lao PDR — factory pricing, genuine parts
-
Gamma source specialists — one of the few teams in Lao PDR licensed to coordinate radioactive material
-
Pedigree from SAPC and LXML — decades of hands-on Lao mining experience
-
ISO 9001:2015 certified by SGS
POWER GENERATION
Lao PDR is the “Battery of Southeast Asia,” and we support the instrumentation that keeps power plants running. We supply and calibrate transmitters for hydropower, thermal, and emerging solar and biomass plants.
Typical applications:
-
Boiler drum level and feedwater flow
-
Steam pressure and temperature
-
Cooling water flow and conductivity
-
Turbine bearing temperature monitoring
-
Emissions monitoring sensors
We provide on-site calibration during plant shutdowns, commissioning support for new units, and 24-hour response for critical instrument failures.
WATER & WASTEWATER
Clean water is a national priority. We supply the measurement and control instrumentation used by municipal water utilities, industrial wastewater treatment plants, and bottled water producers across Lao PDR.
Typical applications:
-
Raw water and treated water flow (magnetic flow meters)
-
Turbidity, pH, conductivity, dissolved oxygen
-
Chlorine and ozone residual monitoring
-
Sludge level in clarifiers and thickeners
-
Pump station pressure and level
We help operators meet WHO drinking water standards and Lao environmental discharge regulations. Calibration and certification documentation is included with every service visit.
OIL & GAS
We support fuel depots, LPG terminals, and natural gas distribution across Lao PDR with high-accuracy custody transfer and process measurement.
Typical applications:
-
Coriolis mass flow meters for fuel custody transfer
-
Tank gauging — radar and servo level
-
Pressure and temperature for pipeline monitoring
-
Gas chromatograph and BTU analyzer support
-
Safety instrumented systems (SIS) sensors
We supply hazardous-area-certified equipment (ATEX, IECEx)
FOOD & BEVERAGE
From breweries to dairy plants, sugar mills to bottled water producers, we supply hygienic instrumentation that meets food safety standards.
Typical applications:
-
Hygienic flow meters (3-A and EHEDG certified)
-
CIP/SIP temperature and conductivity monitoring
-
Tank level for fermentation and storage vessels
-
pH and dissolved CO₂ for breweries
-
Inline density and Brix for sugar and juice
All hygienic instruments come with material traceability certificates and surface finish documentation required by food safety auditors.
CEMENT & BUILDING MATERIALS
Cement plants run hot, dusty, and 24/7. We supply ruggedized instrumentation built for these conditions, radar level for clinker silos, thermal flow meters for combustion air, and gamma density gauges for raw meal blending.
Typical applications:
-
Silo level for clinker, raw meal, and finished cement
-
Kiln shell temperature scanning
-
Combustion air and fuel flow
-
Bag filter differential pressure
-
Stack emissions (NOx, SO₂, dust)
We coordinate gamma density gauges used for raw meal blending: including the full regulatory paperwork for Lao PDR.
