49. upling compound is applied adequately the pipe is full of liquid transducer spacing agrees with the screen readings and the transducers are installed in the right direction Old pipe with heavy scale inside no signal or poor signal detected how can it be resolved Check if the pipe is full of fluid Try the Z method for transducer installation If the pipe is too close to a wall or it is necessary to install the transducers on a vertical or inclined pipe with flow upwards instead of on a horizontal pipe Carefully select a good pipe section and fully clean it apply a wide band of coupling compound on each transducer face bottom and install the transducer properly Slowly and slightly move each transducer with respect to each other around the installation point until the maximum signal is detected Be careful that the new installation location is free of scale inside the pipe and that the pipe is concentric not distorted so that the sound waves do not bounce outside of the proposed area For pipe with thick scale inside or outside try to clean the scale off if it is accessible from the inside Note Sometimes this method might not work and sound wave transmission is not possible because of the a layer of scale between the transducers and pipe inside wall Why is there no CL current loop output Check if the desired current output mode is set in Window M55 See if the CL is powered off by CL Off settings Open the electronics e
50. w indification is driven to zero This function can prevent the flow meter from reading flow after a pump as shut down but there is still liquid movement in the pipe which will result in totalization error Generally 0 01m s is recommended to enter as the low flow cutoff point The low flow cutoff value has no relation to the measurement results once the velocity increase over the low flow cutoff value 5 3 Zero Setting Once zero flow occurs a zero point is established i e as the measurement value reaches zero flow it indicates as zero It is necessary to establish the true zero flow condition and program that set point into the instrument If the zero set point is not at true zero flow an offset will occur For an ultrasonic Flowmeter the measurement difference from zero point cannot be ignored under low flow conditions It is necessary to perform a zero set calibration to improve low flow measurement accuracy Set Zero in Menu42 press Ener wait for the processing indication at the bottom right corner of the screen to reach 0 Performing Set Zero with under flowing conditions may cause the flow to be displayed as 0 If so it can be recovered via Menu 43 5 4 Scale Factor Scale factor refers to the ratio between actual value and reading value For example when the measurement is 2 00 and it is indicated as 1 98 on the instrument the scale factor reading is 2 1 98 This means that the best scale factor constant is
