Magnetostrictive Hydrostatic Level System
MAS-MHLS magnetostatic level is a high-precision liquid level measurement sensor developed by using magnetostrictive principle. It adopts non-contact measurement method, has long service life, strong environmental adaptability, and does not need regular calibration and maintenance. The product is absolute output and does not need to be reset to zero after restart. It has the technical characteristics of high precision, high stability, high reliability and high repeatability. Standard RS485-Modbus protocol is adopted. The magnetostatic level is a special precision instrument for measuring the relative elevation changes between the various measuring points of the foundation and the building. Widely used in hydropower dams, deep foundation pits, highways, bridges, embankments, oil and gas pipelines, oil storage tanks and other foundation fill structure settlement or floating precision measurement.
Overview
The model MHLS magnetostrictive liquid level system is a high pre-cision static level developed using the principle of magnetostriction. It adopts non-contact measurement method, has long life, strong en-vironmental adaptability, and does not require regular calibration and maintenance. The product is an absolute output, and does not require zeroing when restarting. It has the technical characteristics of high precision, high stability, high reliability and high repeatability. The output adopts the standard Modbus protocol and is the measurement of relative elevation changes between various measuring points of the foundation and structure. It is a special precision instrument that can be widely used in precise measurement scenarios such as settlement or heave of foundation fill structures such as hydropower dams, deep foundation pits, highways,bridges, embankments, oil and gas pipelines, and oil storage tanks.
