Roots flowmeter, also known as girdle flowmeter, is a volumetric flowmeter. It is internally designed to constitute a certain volume of the measurement chamber space, the use of mechanical measuring elements to continuously divide the fluid into a single known volume part, according to the measurement chamber one by one, repeatedly filled and discharged the volume part of the number of times the fluid to measure the total volume of flow. Volumetric flowmeter is a flow meter with a long history, with the upstream flow rate distribution is not sensitive to the high accuracy of measurement, can be used for high-viscosity fluids and directly get the cumulative flow of fluids and other characteristics.
Features:
(1) Long service life: the normal operation period is up to 15 years.
(2) Wide range: different specifications of the flow meter range of 50:1 ~ 243:1.
(3) high precision, high reliability: measurement accuracy is not affected by media conditions, long-term use does not need to be adjusted.
(4) low starting flow rate: different specifications of the flowmeter’s starting flow rate of 0.06m3/h ~ 1.20m3/h.
(5) small pressure loss: different specifications of the flowmeter pressure loss of 0.16kPa ~ 0.55kPa.
(6) structure type more: can choose to use the mechanical counter type (only the total number of working conditions), electronic compensation meter (FCM, temperature and pressure compensation), double display (mechanical counter + electronic compensation meter).
