The right mix is what counts. FRIMO offers tailor-made mix and metering machines including various standardized modules for PU product manufacturing.

We develop and manufacture Venturi tubes and nozzles as individual components or as complete VMF® systems. The VenturiMasterFlow® measuring system, VMF® for short, is used for the precise measurement of air or gas volume and mass flows 100,000 m³/h The flow measurement by means of a Venturi tube or Venturi nozzle is characterized by high measuring accuracies up to 0.5% MW and a fast response time < 10 ms. A further benefit is the high long-term stability of the measuring element.

We offer you standardised complete systems for the measurement of volume & mass flows. We use measuring elements that have established themselves within previously built customer-specific test benches and convince with high measuring accuracy. We develop and manufacture Venturi tubes and nozzles as individual components or as VMF® complete systems. The VenturiMasterFlow® measuring system, VMF® for short, is used for the precise measurement of air or gas volume and mass flows of 100,000 m³/h. The core of the VMF® system is the FlowProcessor, a PC system with the corresponding data acquisition hardware. Venturi nozzles convince by a low remaining pressure loss and are suitable for flow measurement of gases with high temperatures. The software developed under LabVIEW is operated either via touch screen or with mouse and keyboard.

The rotary gas meters GM4 and GM16 meet the highest demands for reliable and precise reference measurement of smallest quantities up to 0.01 m³/h. They operate according to the direct displacement principle (RPD - rotary positive displacement), in which two counter-rotating pistons convey a fixed volume from the inlet to the outlet of the gas meter with each full revolution. Due to the specially shaped pistons, absolutely pulsation-free operation can be achieved (patent pending). They achieve an excellent measuring accuracy of 0.5 % MW + 0.005 % EW. Both versions are suitable for operation up to 6 bar overpressure. With continuous, absolutely pulsation-free and highly precise flow measurement, the reference gas meters from Ehrler Prüftechnik are the gold standard in the field of small volume measurement. Features: Reference measurement of small flow rates Continuous and absolutely pulsation-free Overpressure operation Excellent measurement accuracy Robust & compact design

The test bench is designed for calibration with critically operated nozzles of domestic gas meters or others such as diaphragm gas meters, ultrasonic meters, thermoelectric gas meters. The test bench is specially designed for the calibration of domestic gas meters (bellows gas meters, ultrasonic meters, thermoelectric gas meters). The test bench is modular - 1x6 to 4x6 clamping positions for the gas meters can be combined. Due to the modular design 1 to 12 gas meters can be tested simultaneously. In parallel, up to twelve additional test pieces can be adapted, run in and leak tested. A magazine consisting of three critical nozzles is used as flow transmitter. Optionally, a nozzle drum with nine combinable nozzles can be used. This allows the generation of up to 512 different flow points with highest accuracy.

Whether for canisters or bottles with good stability, our high-quality metering pumps have an output from 10 until 30 ml. We have the matching closure sizes, also with tamper evident protection available in 38, 43 and 45 mm.

Large heat and flow meters are often used continuously for decades after an initial calibration at external test benches. A recalibration of these meters within their actual operation conditions was not possible so far. In the best case scenario those flow meters are unmounted and recalibrated on an external test bench. Drawback of this method is an interruption of supply in addition to its already high costs. Furthermore, calibration conditions can differ greatly from actual operation conditions compared to test bench conditions, so even if calibrated, the measurement uncertainty in operation remains fairly unknown. This often leads to more difficult fluid distribution optimizations and leaves billing fairness to a gamble. More precisely measured values of flow sensors may uncover hidden saving potentials within the fluid distribution system and allow more exact performance indicators, improving energy efficiency.
