Introduction

Flow

Every day, enormous volumes of liquids and gases—including oil, natural gas, water, hydrogen, and various emissions—are produced, transported, and distributed around the globe. Flow meters for gases and liquids are essential for accurate billing processes. Our measurements go beyond simple quantity, often encompassing quality parameters such as calorific value or pollutant levels. Even a measurement error as small as 0.1% can lead to losses of millions of euros annually on large oil and gas pipelines. Therefore, reliable measurements, fully traceable to international standards, are crucial for asset owners and operators. Moreover, precise calibrations are highly valued in other sectors, including the process and chemical industries as well as power generation facilities.

Geocore and flow

Drawing on our extensive expertise, Geocore has earned a stellar international reputation in the oil and gas industries. We offer a diverse range of flow and liquid volume measurement services to clients worldwide, including manufacturers of measurement equipment, utility providers, oil and gas producers, as well as companies involved in gas transport and distribution. At the European level, we are actively engaged in several research initiatives, including projects focused on Liquefied Natural Gas (LNG). Our specialists also contribute to international working groups such as the BIPM Working Group on Fluid Flow and EURAMET TC-Flow, which strive to harmonize measurement practices across Europe. In our operations, we implement the Dutch measurement standards for flow that are based on fundamental quantities—mass, length, density, and time. Our liquid and gas laboratory regularly compares these standards with those from other national metrology institutes to ensure they meet international benchmarks. Additionally, we determine liquid mass and density for volume measurements, maintaining traceability to established national standards for mass and density.

Consultancy

We offer expert guidance to both manufacturers and end users, helping them refine their measurement and inspection practices to enhance the overall quality of their processes and products.

Customisation

Calibration

Flow calibration services

Precise and verifiable flow measurements are essential in transactions with significant financial implications. Beyond the basic flow measurement, factors such as calorific (heating) value, temperature, viscosity, and pressure are crucial for minimizing uncertainty. Geocore is equipped with advanced facilities to calibrate a wide range of instruments—from volume devices and pipe provers to flow meters. By analyzing the complete measurement system, we assess its accuracy and overall uncertainty, ensuring that our measurements for volume, mass, and flow are as precise as possible.

Calibration of flow meters

At Geocore, we offer calibration services for a diverse array of flow measurement devices. Our expertise covers turbine, rotor, electromagnetic, Coriolis, vortex, soap membrane, and ultrasonic flow meters—both in our laboratory and directly on site. We also calibrate instruments such as anemometers, mass flow controllers, mass flow meters, laminar flow elements, rotameters, drum meters, and bellows meters. Our facilities are capable of handling a wide range of measurement values. During laboratory calibrations, each flow meter is compared against a recognized measurement standard to evaluate its error and overall uncertainty. In addition to liquid and gas flow meters, we also provide calibration services for air velocity meters.

Calibration of volume instruments and pipe provers

Numerous companies rely on volume instruments and pipe provers for calibrating their field measurement systems. At Geocore, we focus on ensuring these devices are calibrated with precision so that every reading is directly linked to globally accepted unit standards.
