The OI-MV Series Micro Flow Meter, manufactured by Metroval, was developed for applications that require high accuracy in the measurement of extremely low flow rates and act in a wide measurement range, the equipment stands out for its ability to maintain accuracy even in the face of significant variations in fluid viscosity. Designed for demanding industrial environments, the OI-MV guarantees accurate results, ideal for chemical injection systems and high-precision processes.
Its positive displacement operation ensures that each drop is accounted for stably. Thanks to its solid construction and excellent dynamic response, the instrument operates masterfully in high-pressure conditions.
The OI-MV Series Micro Flow Meter operates with an accuracy of ±0.5% and repeatability of ±0.1%, covering flow ranges ranging from 0.002 to 450 l/min. Its modular construction allows the choice of Aluminum, 303 Stainless Steel or 316 Stainless Steel bodies, with stainless steel gears and bearings and PTFE (Teflon®) or FKM (Viton®) seals. The instrument can be configured for bidirectional measurement and accepts the addition of non-intrusive Hall effect sensors with explosion-proof certification, as well as displays and electronic modules for totalization and remote control.
It is a device designed for accurate measurements at micro flow rates, combining compact construction with high mechanical strength for safe operation at high pressure. Developed to meet the requirements of the chemical, petrochemical and oil & gas industries, it operates reliably even in aggressive fluids and complex composition.
Available with transmitters, digital indicators, or direct pulse output, it easily integrates into industrial automation and supervision systems.
The main applications where this type of equipment is essential include:
Chemical Injection on Platforms and FPSO: Proven application in chemical injection racks, where accuracy in the dosing of inhibitors and additives is critical to the integrity of the well and the plant.
Hydraulic and Lubrication Systems: Flow monitoring in power units and centralized lubrication for protection of critical machinery.
Polyurethane and Resins Dosing: Accurate measurement of components in injection and chemical mixing processes where viscosity varies with temperature.
Cylinder Test Benches and Position: Used to measure fluid displacement in hydraulic cylinders due to its bidirectional capability and high resolution.
Aviation Fluid Measurement (Skydrol): Flow control of synthetic hydraulic fluids in hangars and aircraft maintenance lines.
Injection of Additives and Solvents: Ensuring the correct proportion of expensive chemical inputs in continuous industrial processes.
