Method one: Insert a steel tube in the water channel (see Figure 5). The steel tube wall should be thicker, and several holes should be made at different heights on the tube to damp waves and clear the water pressure influence.
- Page 11 Method three: see Figure 7. This method can not only clear water flowing pressure and wave influence, but also filter the sand and mud. Figure 7 9 Operation、Maintenance and Fault Diagnosis 9.1 Operation a) The customer could operate the transmitter without adjustment. b) Please be sure that the installation and electrical connection are correct.
