Condensed water in described pond is distilled water or air conditioner condensate water.
Compared with prior art, the present invention has the following advantages:
One, precise control, security are high: this device is by pressure sensor and liquid level sensor, and be aided with the real-time level monitoring data of temperature sensor, and send to controller to control by optical fiber, effectively control the liquid level in pond, save water resource, guarantee equipment normally runs, for workshop provides the energy.
Two, reliability is high: this device installs a liquid level sensor and a pressure transmitter, and both are arranged in parallel in inside, pond, when liquid level sensor damages, also have pressure transmitter to control, serve the function of dual fail-safe.
Three, simple to operate, raise the efficiency: this device can greatly reduce labour intensity to operating personnel, increases work efficiency.
Four, ensure water quality: adopted distilled water or air conditioner condensate water by the condensed water in pond, both are not calcium ions all, and is provided with screen pack at water outlet, has further purified water quality, has guaranteed the cleaning of condensed water.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment:
As shown in Figure 1, a kind of cooling tower water pool level controller, in order to monitor the water level of pond of cooling tower in real time, the water inlet 3 being arranged on top, pond 1 is connected with cooling tower, the delivery port 4 be arranged on bottom pond 1 is connected with device to be cooled by pipeline, this device comprises the pressure sensor 2 at delivery port 4 place be arranged on bottom pond 1, be arranged on the liquid level sensor 5 on the inwall of pond 1, controller 6, guidance panel 7, the outlet valve 9 being arranged on the water intaking valve 8 on water inlet 3 pipeline and being arranged on delivery port 3 pipeline, controller 6 respectively with pressure sensor 2, liquid level sensor 5, guidance panel 7, water intaking valve 8 is connected with outlet valve 9.
