It adopts full metal structure, which is with thefeatures of small volum, low pressure loss , big range ratio(10-20:1),optional transmitter withHART communication function and installation and maintance convenient.It is widely used invarious industries under the complex and bad environment, which is measuring the flowand controlling the process to the small flow and low flow velocity, and all kinds of harshconditions of medium.

BTLZ series intelligent metal tube floater flowmeter series products, according to differentusers' requirements and different occasions, there are many kinds of measurement form forusers to choose; According to the output form,there areon-site instruction type, fartransmission type, control alarm type; according to the requirements of explosion-proof,it canbe divided into three types: the common type, intrinsic safety type, isolation andexplosion-proof type

BTLZ series intelligent metal tube floater flowmeter adopts the intemational advancedHoneywell without contact and no hysteresis detecting changes in the Angle of magnetic fieldof magnetic sensor, and with high performance MCU, which can realize LCD display:theinstantaneous flow, total flow,loop current.environment temperature,damping time,smallsignalremoval.Optional 4~20mA tranmission(with HART communication),pulse output, highand low limit alarm output function,etc,the type of intelligent signal transmitter has highprecision and reliability,which can fully replace the same type imported instrument, and it alsohas high price performance, parameter standardization online and power failure protection,etcfeatures

BTLZ series intelligent metal tube floater flowmeter's design also takes into account theusers'requiremnts of the process flow ,there are five installation types to select: lower inlet onthe installation type,upper inlet under the installation type , side in side out installation, bottomin side the installation type and horizontal type installations.

Structure and Principle
BTLZ series intelligent metal tube floater flow meter is made up of two parts:

(1)Sensor - measuring tube and floater;
(2)Signal transmitter - indicator;
The sensor has four connecting liquid material :stainless steel, Hastelloy, Titanium, stainless steel lining FEP; The users can choose different touching liquid material to meet the needs ofthe proof pressure of process and anti-corrosion of medium according to the requirements ofthe different process pressure and corrosive medium According to the different measurementrequirements, the users can choose different indicator combination in their selection to realizethe different measurement requirements. The specific indicator form and itscorrespondingfunction, please refer to the indicator table.
Flow rate is measured by the indicator in the transmitter through the coupling of magneticsteel feeling floater's position changes to complete the flow indicator and signal remotetransmission. When the measured medium flowing through the measuring tube from bottom totop, the floater by gravity, buoyancy and fluid velocity to the floater's vertical upward thrust arebalance,floater will be relatively static in a certain position, the position changes with thefloater and taper pipe ring gap area and fluid velocity, the position of the floater iscorresponding to the size of the measured medium flow.
