7. id level mounting hight TH As shown the meter s probe generates wave which hits the level and then is reflected back to the probe After receiving the wave the probe calculates the time interval between generating and receiving wave and works out the measuring distance L The meter s mounting height TH minus L is the current level H Mileage refers to the distance measurable by the meter TH should be less than the mileage Blind area refers to the area which cannot be measured by the meter around the probe The space between the highest level and the probe should be larger than the blind area If the blind area is 0 3m the space between the highest level and the probe must be over 0 3m The probe s generating wave is a spreading process namely there are direction angles to which the attention should be paid in installation Otherwise the wave may hit bumps on pool walls or the channel s edges 3 4 Installation principles 1 The distance between the probe s emitting surface and the lowest level must be less than the measuring range of the meter chosen 2 The distance between the probe s emitting surface and the highest level must be larger than the blind area of the meter chosen 3 The probe s emitting surface must keep parallel to surface 4 Do not install probe at feed or discharge ports positively below and other positions where surface fluctuates fiercely 5 If the poor or tank wa
8. ll is not smooth the probe s installation position must be over 0 3m away from the poor or tank wall 6 If the distance between the probe s emitting surface and the highest level is less than the blind area of the meter chosen it needs to install a extension tube which is over 120mm in diameter and 0 35m 0 50m in length installed vertically and with smooth internal walls The hole on the tank must be larger than the extension tuber s inside diameter Or the tube touches the tank bottom The tuber diameter is over 80mm A hole is made at the tube bottom so as to the surface inside the tube is the same high as that inside the tank Ultrasonic Level Meter 3 5 Installation precautions 1 Where the meter is installed outdoors it s better to install a sun shied so as to prolong the meter s service life 2 Electrical wires and cable protective pipes must be well sealed in order to prevent water accumulation 3 The meter has lightning protection component but when it is used in regions where it thunders frequently it is suggested that a lightning protection device for exclusive use be separately installed at wire inlet and outlet of the meter 4 If the meter is used at place where it is quite hot or cold namely ambient temperature may exceed the meter s working requirement it is suggested that the high or low temperature resistance device be set around the level meter 4 Debugging e w 0 amp 4 1 Keyboard
