1. Sensor of turbine flowmeter
This type of turbine flow product itself does not have on-site display function, only transmits and outputs flow signals remotely. Flow signals can be divided into pulse signals or current signals (4-20mA); The instrument is inexpensive, highly integrated, and compact in size, making it particularly suitable for use with computer control systems such as secondary displays, PLCs, and DCS. This type of turbine flow product is divided into two types: basic type and explosion-proof type (ExdIIBT6). According to different output signals, this type of product can be divided into LWGY - □ N and LWGY - □ A LWGY - □ N sensors: powered by 12-24VDC, three wire pulse output, high level ≥ 8V, low level ≤ 0.8V; signal transmission distance ≤ 1000 meters; LWGY - □ A type transmitter: 24VDC power supply, two-wire 4-20mA output, signal transmission distance ≤ 1000. The intelligent integrated turbine flowmeter adopts advanced ultra-low power single-chip microcomputer technology to develop a turbine flow sensor and a new type of intelligent instrument material information grip meter that integrates display and calculation. It adopts a dual row LCD on-site display and has obvious advantages such as compact structure, intuitive and clear readings, high reliability, no external power interference, lightning resistance, and low cost. The instrument has three-point correction of instrument coefficient, intelligent compensation of instrument coefficient nonlinearity, and can be corrected on site. The high-definition Chu LCD display simultaneously displays instantaneous flow (4 significant digits) and cumulative flow (8 significant digits, with a reset function). Keep all valid data intact for 10 years af
2. Selection of battery powered turbine flowmeter
When choosing a battery powered turbine flowmeter, the first thing to consider is measurement requirements.
. The LWGY series offers multiple specifications to accommodate different applications. For example, for DN40 diesel pipelines, if flange connection is required, the LWGY-40 (FL) model can be selected. Its characteristic is explosion-proof type (Exm Ⅱ CT6 or Exd Ⅱ BT6), ensuring safe operation of the Weina in high-pressure environments. For on-site display and remote transmission of current signals, the LWGY series offers a C-type, which means you will receive battery powered on-site display and 4-20mA two-wire current output function. The accuracy level is 0.5, ensuring the accuracy of the measurement results. The accuracy level option for LWGY is 05. Considering the material of the pipeline, choosing S304 stainless steel for turbine components is the correct choice for 304 stainless steel. In terms of pressure rating, due to the need to withstand a pressure of 16MPa, the H (x) high-pressure version should be selected. In ter
