英国Whessoe Varec公司最近推出一种全新设计的浮子液位计,它可用来测量中转油库、炼油厂、化学制品、饮料等行业散装液体储罐的液位.其测量精度为1mm.该产品配有一个组合式变送器,利用外接传感器来测量温度,通过包括所有标准的Whessoe Varec协议的通信格式把结果传回主机.该产品由于借助于几乎没有摩擦和滞后的带尺装置,其精度与售价昂贵的伺服式或雷达液位计相同,但比常规的浮子液位计高四倍.产品的精度已通过NMI和SIM的认证.它的应用范围可扩大到密封传输领域.它所占用的面积为21cm×22cm,只有标准占用面积的1/3,可直接安装在原液位计的安装位置上,最大限度地减少技改费用.该产品还最大限度地减少运动部件,使常规的三轴运动减少至0～99m(325英尺)带尺装置仅需要的双轴运动,变送器的电子器件通过磁性耦合仓与外界隔离,从而使其保质期达到二年.产品采取就地显示方式,由液晶显示器显示示值.
Whessoe Varec, the UK company, recently introduced a newly designed float level gauge that measures the liquid level in bulk liquid storage tanks in industries such as transit depots, refineries, chemicals, beverages, etc. The measurement accuracy is 1mm. A modular transmitter that measures the temperature with an external sensor and sends the results back to the host computer through a communication format that includes all the standard Whessoe Varec protocols thanks to a tape device with little or no friction and hysteresis, The same expensive servo or radar level gauges, but four times higher than conventional float level gauges. The accuracy of the products has been certified by NMI and SIM, and its range of applications extends to sealed transmission. The area is 21cm × 22cm, only 1/3 of the standard occupied area, which can be installed directly on the installation position of the original level gauge to minimize the technical innovation cost. The product also minimizes the moving parts and makes the conventional triaxial Reduced motion to 0-99m (325ft) Two-axis motion only required by the tape unit, the electronics of the transmitter are isolated from the outside through a magnetic coupling chamber, giving a shelf life of up to two years. Products taken on-site display, the LCD display shows value.
