Four gas detector features: 1, unimpeded flow and moving parts, it will not cause additional energy loss within the measuring tube, it will not cause congestion, suitable for liquid-solid two-phase flow, such as sewage, sludge, slurry, coal slurry , pulp and other measurements. 2, the only contact with the measured medium liner and electrodes, as long as the rational use of lining and electrode materials, we can achieve good corrosion resistance and abrasion resistance, therefore, measure various acid, carbon monoxide gas detector alkali and other chemical solution . 3, installation requirements low. Just before the straight pipe 5D, the straight pipe to the inside diameter of the selected instrument). 4, the measurement accuracy from the fluid density, viscosity, temperature, pressure, and changes of electrical conductivity, and measure the forward / reverse flow in both directions, which is very accurate flow measurement means is provided. Combustible gas detector 5 meter power consumption. Less than 6, the converter has good interchangeability, having to re-implement flow calibration accuracy can be achieved. Because electromagnetic flowmeter has a series of advantages, so get in the more widely used in various industries, the main technical parameters of the instrument of choice for liquid flow measurement: the conductivity of a two-way flow of current output range two-way, full isolation, (load resistance 0 ~ ( Open load resistance, including the frequency of the output limit setting. transistor open collector output pulse outputs with optical isolation up to the upper limit equivalent to the pulse width of the pulse. band optically isolated open collector output transistor alarm output transistor collector with optical isolation maximum collector current of http://www.dingdinggroup.com/ alarm output, forward and reverse flow conditions set open collector output. above three output external power supply is turned on not more than 3
