气体转子流量计 用于封闭管道中气体或蒸汽的流量测量，在过程控制中的广泛应用，特别适合中小流量的控制和测量 。 DX-LZ series gas rotor flowmeter is used to measure the flow of gas or steam in closed pipelines. It is widely used in process control, and is especially suitable for small and medium flow control and measurement .
是由锥 管、浮子、指示器、转换器组成。 Gas rotor flowmeter is composed of cone tube, float, indicator and converter. 磁钢传递给指示器就地指示流量或再由转换器转换成相应的电信号(二线制4-20mA,三线制0-10 mA,四线制4-20 mA、0-20mA) 可与 DDZ-Ⅱ、 DDZ-Ⅲ型电动单元组合仪表， I系列、EK系列等仪表匹配，也可与计算机联网实现流量的远距离显示，记录、调节，积算和控制。 When the fluid flows into the cone float and rises, when its lift M is balanced with gravity G, the displacement of the float is transmitted to the indicator through the magnetic steel to indicate the flow rate on the spot or converted by the converter into the corresponding electrical signal (two-wire system 4-20mA, three-wire system) 0-10 mA, 4-wire 4-20 mA, 0-20mA) can be matched with DDZ-Ⅱ, DDZ-Ⅲ type electric unit combination meters, I series, EK series and other meters, and can also be connected to a computer to achieve flow rate Long distance display, record, adjust, accumulate and control.
1. Reasonable design and reliable operation. The indicator part is a maintenance-free component, which is resistant to corrosion, high temperature and high pressure, dust-proof, drip-proof and explosion-proof.
和实际工作状态的流体流量(根据用户提供、流量、温度、密度、压力等参数由计。 According to the user's requirements, the standard state flow rate and the actual working state fluid flow rate can be indicated at the same time (based on user-provided parameters such as flow rate, temperature, density, and pressure).
Computer calculation is completed) can also make 2-3 kinds of scale instructions, the output signal of the paperless recorder is consistent with the scale and linear.
，输出频率信号并可显示累积流量。 2. Output analog signal 0-10mA, 4-20 mA or 0-20 mA can be equipped with our factory analog signal-frequency converter , output frequency signal and display cumulative flow.
和尺寸为方便设计院设计，基型流量传感器安装高度为250mm,过滤器安装高度为100mm和50mm二种，亦可按客户要求定制。 3. There are various forms of structure and dimensions for connecting the pipeline and the flow sensor. For the convenience of design institute design, the installation height of the basic flow sensor is 250mm, and the installation height of the filter is 100mm and 50mm. It can also be customized according to customer requirements.
4. Flow sensor, in addition to the base material 1Cr18Ni9Ti, 0Cr18Ni9Ti 0Cr18Ni12Mo2Ti (molybdenum titanium); (nickel-based alloy (hastelloy), such as 0Cr16 Ni60Mo16W4; lined with polytetrafluoroethylene (PTFE) 4F or 46F, glass, Rubber etc.
5. Each performance index is not lower than similar foreign products.
气体转子流量计 耐高温可达350℃，小口径耐压可达10MPa以上。 6. Gas rotor flowmeter can withstand high temperature up to 350 ℃, and small caliber withstand pressure above 10MPa.
，亦可适用于较大脉动的流体测量。 7. In order to prevent the error caused by the jump of the float when measuring gas or steam, a damper is specially designed , which can also be applied to the measurement of larger pulsating fluids.
8. The inlet and outlet positions of the flowmeter are: bottom-up; left-right (flat); right-left (flat); bottom-up horizontal; bottom-up horizontal;
9. According to the user's needs, there are indication type; remote transmission; upper and lower limit alarm devices; on-site cumulative display; insulation; cooling jacket; and various specifications and filters are available.
