Chapter 2 Installation
solved by installing a section of nozzle or installing the entire measuring sleeve. It
should be noted that after the sensor is placed in the nozzle, the blind area will
increase by about 50 ~ 100%, and the factor of increasing the blind area should
be taken into account.
Therefore, if the original probe blind area is 0.50 meters when the nozzle is used,
the blind area will increase to 1.00 meters when the nozzle is placed inside the
nozzle.
nozzle used for measuring drainage well.
Ordinary water wells (including water source wells and deep water wells) generally
have small diameters, and measuring sleeves can be installed to achieve the best
measuring effect. The inner wall of measuring sleeves must be smooth (e.g. PVC
or PE waste water pipes) and the inner diameter ≥150mm (within the measuring
range of 4 meters). If the takeover exceeds 4 meters, the manufacturer shall be
consulted. As long as the measuring nozzle can be kept clean, free of adhered
media and free of seams inside, measurement can be made. The measuring
sleeve shall be soaked in the medium all the time so as to ensure accurate
measurement in the measuring nozzle.
