Gate opening (height) load gauge: WTM-AS

1. Introduction and Application of Gate Opening Meter WTM-AS:

Model：WTM-AS

The gate measurement and control system is the core equipment used in water conservancy projects to monitor and control the operating status of gates. It collects data such as water level, flow rate and gate opening degree in real time through automation technology, helping managers achieve precise dispatching and ensuring the safe and efficient operation of water conservancy facilities.

In scenarios such as water conservancy hubs, reservoirs, and river management, gate control directly affects functions such as flood control and drainage, as well as irrigation and water supply. For instance, after a large reservoir adopted the micro-special gate measurement and control system, the management personnel could complete the water level adjustment through remote operation, avoiding the time-consuming and risky manual on-site operation, and at the same time reducing the waste of water resources caused by operational errors.

2. The micro and special gate opening instrument WTM-AS is applicable to the following scenarios:

It is mainly used for: automatic measurement and control instruments for measuring, displaying and controlling the lifting capacity and opening degree (height) of hoists, gantry cranes, hoists and other lifting equipment.

3. Relevant configurations of the gate opening instrument WTM-AS:

The following accessories are based on the application in the hoist shown in the above picture. The safety configurations of different lifting equipment are not the same.

Height encoderAn encoder is a device that encodes signals or data and converts them into a form suitable for communication, transmission and storage. The opening degree instrument uses the height signal obtained by the encoder to receive, sample, analyze, process, identify, display and control.

Weight sensorThe selection of the weight sensor is determined by the actual lifting structure of the crane. For specific details, please consult the customer service. Commonly used weight sensors include PY side pressure weight sensor, ZX pin weight sensor, BH plate ring weight sensor, SHL three-pulley weight sensor, QCX bearing housing weight sensor, etc.

Travel limiterAn encoder is a device that encodes signals or data and converts them into a form suitable for communication, transmission and storage. The opening degree instrument uses the height signal obtained by the encoder to receive, sample, analyze, process, identify, display and control. (This configuration is optional.
