Product Introduction
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.
Product Advantages

FEP/PFA lining, steel mesh reinforcement, suitable for strong corrosive media such as chlorine, acids, and alkalis.
Food and pharmaceutical grade polishing, quick-release clamps, and a no-dead-angle design.
Optimized damping structure, less prone to jamming, and stable measurement.
Range ratio up to 20:1, with anti-jamming positioning holes on the lower guide.
4.Intelligent Circuits and Software
Independent hardware + Embedded software with independent intellectual property rights
Supports HART communication
One-key zeroing, LCD display, upper and lower limit alarms, pulse output, explosion-proof type optional
5.Structure and Protection
Dual-chamber safety design of the indicator, wiring does not move the main chamber, reducing the risk of failure
Optimized magnetic coupling structure reduces the influence of the geomagnetic field, making the zero point more stable
Electromagnetic damper suppresses pulsating current jitter, improving stability
