The PTFE lined magnetic float level gauge consists of a detection float, transmission components (measuring steel strip, guide elbow, etc.), and an instrument body. The indicator consists of a sprocket, winding wheel, transverse torque spring, gear device, pointer, and dial. The transmitter matched with the liquid level gauge is connected to the sprocket shaft on the indicator body through a connecting mechanism. The float tracks changes in liquid level with constant traction and remains floating on the liquid level. The float is wound onto the winding wheel with stainless steel strips spaced uniformly through perforations, and the constant torque spring is combined with the winding wheel as a whole.
A constant torque spring drives the winding wheel and steel strip to rotate together to form a self balancing mechanical system in order to maintain a constant torque. The float rises and falls according to the change in liquid level. The stainless steel strip is connected to the float to drive the sprocket to rotate together. The sprocket rotates to mesh with the perforated belt, and the rotation of the sprocket corresponds to the rise and fall of the float. Therefore, once there is a change in liquid level, it is converted into a change in the rotation angle of the sprocket shaft. The rotation angle of the sprocket shaft is transmitted to the angle conversion unit, micro switch alarm, starting device, electric device, digital BCD, etc. Complete remote data transmission through the receiving unit.
Installation steps and precautions for PTFE lined magnetic float level gauge:
1. Install casing and header brackets according to different storage tanks. (It is recommended to use stainless steel or galvanized material for the casing, but do not use carbon steel casing).
When the instrument arrived at the site, all the steel strips were pulled out and coiled together, protected by black rubber sleeves. To prevent damage to the steel strip during installation, first remove the fixing screws and rubber protective sleeve on the manual wheel, and slowly retract the steel strip into the header. Note: Control the recycling speed, as the force of the coil spring on the steel strip is very strong for recycling; Be careful not to twist or deform the steel strip. ）The normal recycling of steel strip exceeds the measurement range, which can be read from the indicator dial. Cut off the excess part of the steel strip according to the on-site situation. If the length of the recycled steel strip is less than the measurement range, adjust it according to the coil spring adjustment method described later.
3. Open the top cover of the 90 ° elbow, place one section of the steel wire rope with the connecting piece into the sleeve, and insert the other end through the sleeve into the storage tank. When placing the wire rope, make sure it is on the pulley.
