在使用流速仪测流时,必須有一根懸索和二根电线,用來懸吊流速仪及鉛魚和接通全部电路。由于水流对懸索和电綫冲击的关系,使得懸索產生偏角,并且会使电綫承受很大的張力,很容易產生电綫脫头或內部断綫等毛病。尤其在洪峰测量时,由于电线脫头斷綫,往往影响到測流 When using a flowmeter, there must be one cable and two wires to suspend the flowmeter, lead fish and all electrical connections. Due to the water flow on the suspension cable and the impact of the relationship, making the cable have declination, and will make the wire under great tension, it is easy to produce wire disconnection or internal disconnection and other problems. Especially in the peak measurement, due to the wire off the head, often affect the flow measurement
