Precautions for selection of level switch

Common level switches include vibrating level switches, RF admittance level switches, rotary resistance level switches, etc. Because all kinds of level switches have their own characteristics and scope of application, even the same level switch, in the face of complex working conditions, also need to choose different models to adapt to it, in order to achieve better level measurement effect, the selection of level switch is very important. So, the level switch in the selection of the need to pay attention to what are the following points:

Problems that Magnetic Level Gauge May Encountered in Installation and Use

When installing the magnetic level gauge, the magnetic level gauge must adhere to the vertical condition. A ball valve should be installed between the magnetic level gauge and the container lead pipe to facilitate the maintenance, disassembly and cleaning of the level gauge. The liquid medium to be measured should not contain solid impurities or magnetic substances, otherwise it is easy to form a jam on the float and affect the accuracy of measurement.

Working Principle and Installation and Commissioning of Buoy Level Gauge

Buoy level gauge is a field instrument that uses buoys as measuring elements and indirectly indicates the level of the measured medium in open or low-pressure containers through a group of roller slides and steel wires. It is suitable for the liquid level measurement of the corrosive medium tank of petrochemical storage tank system, tank, oil field, oil depot and other industries, as well as the water tower (tank) of general enterprises and civil buildings. Solve the liquid level measurement of the storage tank and the difficulty of measuring with a steel ruler for manual topping, and can obtain accurate measurement results, the measured medium can be acidic, alkaline or high viscosity.

Notes and characteristics of level gauge

The correct selection of the liquid level gauge can ensure the better use of the liquid level gauge. What kind of liquid level gauge should be selected according to the physical and chemical properties of the fluid medium to be measured. The diameter, flow range, lining material, electrode material and output current of the level gauge can be adapted to the nature of the measured fluid and the requirements of flow measurement.

Product Overview of Buoy Level Gauge

The buoy level gauge is a mechanical level measuring instrument. When the liquid level in the measuring container is at a certain position, the buoy weight W, the weight W1 of the heavy hammer pointer and the buoyancy F of the buoy immersed in the liquid, the friction force F and the four forces in the whole system are in equilibrium (I .e. W-F- W1-f = 0). When the liquid level rises, the float is floated along the guide cable due to the traction cable, and the liquid buoyancy, F increases. The four forces of the original balance system are out of balance, and the heavy hammer pointer slides downward under the action of gravity. At the same time, the rising height of the liquid level is also continuously indicated on the scale. Similarly, it can be explained that when the liquid level drops, the buoyancy F of the float

How to Correctly Overhaul and Maintain the Installation of Heavy Hammer Buoy Level Gauge

The faults of the heavy hammer buoy level gauge include zero drift, inaccurate fullness, most electronic circuits affected by temperature, or vibration in the installation environment of the instrument. By adjusting the circuit parameters and calibrating the instrument, the process level changes, but the buoy level indicator does not change. Many fastening bolts are not fastened, or the bolts are loose due to vibration. The loosening of the connecting shaft causes the transmitter to be separated from the buoy shaft. The heavy weight buoy level gauge shows slowly. It may be that the bearing is damaged due to excessive friction. Aging and leakage at the root of the sealing disc are also common faults.
