Note automatic tank gauge systems

automatic tank gauge systems in order to ensure the correct selection level gauge to better use. Choice of what kind of instrument should be based on the level of physical and chemical properties of the test to determine the fluid medium? Make level gauge diameter, flow range, lining materials, electrode materials and output current? Can adapt measured fluid the nature and flow measurement.
1, precision function tests
Accuracy classes and functions according to measurement requirements and use the occasion to select the instrument accuracy class, so economical. Such as for trade settlement, custody transfer and energy measurement products occasions, should choose higher level of accuracy, such as 1.0, 0.5, or higher level; process control applications for select different accuracy classes according to the control requirements; some only about the process flow is detected, without making precise control and measurement of the occasion, you can choose a slightly lower level of accuracy, such as 1.5, 2.5, or 4.0, then you can choose inexpensive plug-in level gauge.
2, measurable media
Medium flow rate measurement, the instrument measuring range and caliber of the media in general, the level meter full scale flow can be measured in the medium velocity 0.5-12m / s range selection, the range is wide. Select the meter size (diameter) is not necessarily the same process piping,fuel card management system should be considered whether the measured flow rate range within the range of flow rates to determine that when the pipe flow rate is low, can not meet the requirements of the flow meter or when this flow rate measurement accuracy can not be guaranteed, the We need to narrow instrument caliber, thereby increasing the flow rate of the tube to obtain satisfactory measurements
