Vortex flow meters are common in the flow measurement of fluids in the industrial pipeline, such as gases, liquids, vapor and other media. This kind of device features small pressure loss, large measuring range, high precision, and is almost not affected by parameters such as fluid density, pressure, temperature, viscosity, etc.

Due to the compressibility of the gas, its flow measurement by vortex flow meters is more complicated than that of the liquid. Its output signal is not only related to the input signal, but also the gas density, and the density of the gas is the function of temperature and pressure. Therefore, the gas flow measurement is generally involved with temperature and pressure compensation.The density of vapor is not only related to temperature and pressure, but also to humidity. In recent years, new types of vortex flow meters have been developed and upgraded, making the temperature and pressure compensation for gas flow measurement simple and accurate.

Holykell standard vortex flow meter can measure medium of -20°C~+120°C, versions for higher temperature can be customized. With the temperature and pressure compensated, it can work within a wide temperature range with high accuracy provided. It's an ideal flow meter.
