具有结构简单、工作可靠、适用范围广、测量准确、安装方便等特点,具有耐高温、耐高压、DXLZ系列金属转子流量计有普通型和防腐蚀型,以上两种类型均分为现场指示型(DXLZZ-)和电远传型(DXLZD-)、普通型流量传感器、仪表材料为(1Cr18Ni9Ti)、防腐型为(1Cr18Ni9Ti)内衬PTEF。 DXLZ series metal float flowmeter has the characteristics of simple structure, reliable operation, wide application range, accurate measurement and convenient installation. It has high temperature resistance and high pressure resistance. DXLZ series metal rotor flowmeter has ordinary type and anticorrosion type. They are divided into on-site indication type (DXLZZ-) and electric remote transmission type (DXLZD-), ordinary flow sensor, instrument material (1Cr18Ni9Ti), and anti-corrosion type (1Cr18Ni9Ti) lined with PTEF. 测量的介质中含有铁磁性颗粒,就应在流量计入口处安装磁过滤器。 If the medium measured by the metal float flowmeter contains ferromagnetic particles, a magnetic filter should be installed at the inlet of the flowmeter. Its material should be the same as the corresponding flow meter.
Main technical parameters (1) Basic measurement range: water (20 ℃) 2.5-150000L / h
Air (20 ° C, 0.1013MPa) 0.07-4000Nm3 / h
Range ratio: 10: 1
Accuracy: 1.5 / 2.5
Working pressure: ≤6.4MP

的保养:1.必须保证仪表的清洁,特别是仪表中孔板、椎管的表面和浮子必须保持清洁,因而仪表使用一段时间后应取下清洗。 Maintenance of metal tube float flowmeter : 1. The instrument must be clean, especially the orifice plate, the surface of the spinal canal and the float must be kept clean, so the instrument should be removed and cleaned after using it for a period of time. 2. The two covers of the indicator must be sealed to prevent dust from entering and affecting normal work. 3. If the operation of the meter is unstable, the main reason for the pointer to jump is to consider the possibility that the medium has two-phase flow (that is, the liquid phase and gas phase coexist) in addition to the pulse of the flow itself. This will ensure the stable operation of the instrument.
