BTLZ series intelligent metal tube rotor flowmeter is a variable area flowmeter based on float position measurement. It adopts all-metal structure, small size, small pressure loss, large range ratio (10~20:1), optional transmitter with HART communication function, easy installation and maintenance, etc. It is widely used in various industries in complex and harsh environments, for flow measurement and process control of small flow, low flow rate and various harsh media conditions.
The BTLZ series intelligent metal tube rotor flowmeter has various measurement forms. According to the output form, it is divided into local indication type, remote transmission output type and control alarm type. According to the explosion-proof requirements, it is divided into ordinary type, intrinsically safe type and isolated explosion-proof type.
Its design and production provide installation methods such as bottom in and top out, top in and bottom out, side in and side out, bottom in and side out, and horizontal installation. It can be equipped with 4~20mA remote transmission output (with HART communication), pulse output, upper and lower limit alarm output and other functions. This intelligent signal transmitter has high accuracy and high reliability, and can replace imported instruments of the same type with high cost performance.
