It is scheduled on water level detecting stent 5, and the liquid level of the bottom big opening end face testing liquid of its electromagnetic horn 3, for to be measured
The water level of liquid is detected.But no matter which kind of mounting means, existing indicator water gage after installation is complete, in later maintenance all
Inconvenient arbitrarily adjustment setting angle, this installs occasion that is improper and needing to carry out secondary installing to indicator water gage for the first time
It is added significantly to the difficulty of installation and debugging.
To sum up, there are antenna is easy to fall off, antenna disqualification rate is higher, production cost is high, peace for existing indicator water gage
Dress angle such as is not easy to adjust at the drawbacks, therefore is badly in need of carrying out structural adjustment to indicator water gage.
