High precise LCD display metal tube flow meter   is a kind of high performance,high reliability of the flowmeter.Widely used in petroleum.chemical industry,food,electricity,steel,paper making,metallurgy,watersupply and  drainage, petrochemical, medicine industry etc.

Product Features:
 1.Strong metal structure design
 2.Suitable for various industries of gas and liquid measurement
 3.Different flow shell structure design, it can be used in high temperature environment without increasing components.
 4.Special design of conical measuring tube, its measuring range and measuring line is wider and better.
 5.We can offer flange connection, clamp, thread and other process connection modes, which is suitable for most of the factories application requirements
 6.Measuring part materials can be selected: stainless steel, titanium, Hastelloy,  PTFE, FEP, etc
7.A specially designed magnetic coupling system, can improve the measurement precision and stability obviously.
The features of for transmission output of the instrument:
1.The large LCD display can display the instantaneous flow and total flow at the same time and also display the instantaneous flow simulation.
The upper display the instantaneous flow, lower display the total flow
Instantaneous flow range: 0.000-99999
Cumulative flow display range: 0.00-99999999
Current display range: 3.80-21.00 mA
Instantaneous flow percentage display: 0-100%
Pointer Angle Range: 0.00 to 90.00 °
Ambient temperature range: - 20 - + 80 °C
The cumulative small signal removal range: 0-10%
Damping time setting range: 0 to 10 seconds
A variety of optional instantaneous flow and total flow unit, after the unit switching, the range is automatic conversion.
2.The upper can be switched on the display: the instantaneous flow , loop current, percentage of the instantaneous flow and cumulative small signal removal, damping time, the current environment temperature, and the pointer rotation angle,etc information, and it also can display the commonly used symbols and engineering units, which will not affect the discharge total flow and instantaneous flow simulation of the display at the time.
3.The LCD displays the flow range of the instantaneous flow, according to the measurement medium at the scene. It can be corrected.
4.Double LCD display’s power consumption is microamps level, which meets the requirements of the intrinsic safety explosion-proof.
5.Accuracy: <+/-0.5%, the temperature drift: <+ /- 0.1%/ 10 °C
6.Perfect power-failure protection function, when the power failure, it can save the current total flow (the total flow of sampling period is 0.3 s), and applied the advanced six levels of data backup mechanism, which makes the data less impossible.
7.LCD can select the backlit display
8.Transmitter can output: two-wire system, 4-20 mA signals, and has nothing to do with the LCD display function whether it has or not.
9.Support the battery power supply function, it uses different types of rechargeable batteries according to different application, and it can be normal work 3 to 12 months at one time charging.
10.It is no need to open the cover. It uses the magnetic pen operational way and also keeps the normal buttons. (it can be made according to customers’ requirements)
11.By HART protocol and the upper computer software or hand-held communication. Upper computer connects with the meter by using HART modem, which can dynamically monitor the instantaneous flow and total flow, loop current, percentage of the instantaneous flow, etc(only for two-wire system,4-20 mA instrument with HART communication function)
12.By HART protocol, hand-held or upper computer software can be used in the operation of the flowmeter for some or all of the configuration (only for two-wire system 4-20 ma instrument with HART communication function)
