Wireless level sensor is a high-precision, low-power wireless liquid level detection instrument, which consists of input liquid level sensor, signal processing circuit, communication module and power module. It uses a high-capacity, high-energy lithium battery, radio frequency radio transmission data. Installation is simple, easy to use, no need site wiring, leaves out the conventional instrument wiring bypass trouble, save manpower and construction cost, especially suitable for unwired and unpowered application site.

How to choose concrete pump truck
1, the selection of concrete pump truck. Should be based on the object of concrete works, the characteristics of the maximum delivery requirements, the maximum transmission distance, concrete pouring plan, concrete pump form and the specific conditions to be considered. 2, the performance of concrete pump truck varies with different models, the selection of models in addition to considering the amount of concrete pouring, but also consider the type of construction and structure, construction technology requirements, site conditions and the surrounding environment. Usually the main performance parameters of concrete pump should be consistent with the construction needs or slightly larger, if the capacity is too large, the utilization rate is low; too small, not only can not meet the construction requirements but also accelerate the loss of concrete pump truck. 3, due to the flexibility of concrete pump truck, and the higher the boom height, the greater the pouring height and fabric radius, the stronger the construction adaptability, on the construction should try to use high boom concrete pump truck. Boom length of 28 ~ 36m concrete pump truck is a large volume of products on the market, accounting for about 75%. Long arm concrete pump truck will be the construction of the main models. 4, with an annual output of 10 to 150,000 m3 of concrete mixing plant, to be equipped with 2 to 3 concrete pump truck. 5, the number of concrete pump truck used, according to the amount of concrete pouring, the actual delivery of single machine and construction work time calculation. For those one-time concrete pouring large amount of concrete pumping construction, in addition to the calculation to determine, there should be some reserve. 6, Because the concrete pump truck is limited by the carrying capacity of the automobile chassis, the cost increases greatly when the height of the boom exceeds 42m and is limited by the construction site space. Therefore, it is seldom used. 7, concrete pump truck product performance in the selection should adhere to a high starting point. If the choice of high value concrete pump truck, the standard requirements of their products must also be increased. The quality of the main components of the product, from the intrinsic quality to the external quality should be compatible with the high value of the vehicle. 8, concrete pump truck with full hydraulic technology, so to consider whether the hydraulic technology used is advanced, how the quality of hydraulic components. Because of its power from the engine, and the general truck used in the car chassis engine, so in addition to considering the engine performance and quality, but also consider the performance of the car chassis, carrying capacity and quality. 9, Concrete pump operation control system with manual, wired and wireless control, easy and flexible wired control, wireless remote control can be long-distance operation, once the circuit fails, manual operation can be used. 10, concrete pump truck as a special vehicle, because of its special features, safety, mechanical properties, manufacturers of after-sales service and spare parts supply should be requested. Otherwise, once an accident occurs, it will not only affect the progress of construction, but also will produce unimaginable consequences.
