Flow meters 4 20ma

NBLB target flow meter is a new generation of flow meter developed by our company. It adopts a new force-torque tube-corner conversion mechanism, transfers the angle through the torque tube, then measures the angle through the high precision Hall sensor and outputs the voltage signal corresponding to the flow change and outputs the standard 4 mA~20 mA square (linear) current analog signal. The instrument has the modern popular enclosure design, the shape is beautiful and each working chamber is isolated, uses the non-contact angle measurement technology to avoid the strain sensor force deformation, safe and reliable.

Temperature & pressure compensation vortex flowmeter adopts Karman vortex street principle, and the sensor has built-in piezoelectric crystal and integrated temperature and pressure measurement function, which can measure gas temperature and pressure, ensure more accurate volume or mass flow.

MTFC series purge device use micro metal pipe float flow meter and constant current valve to form a purge device, which realizes the steady output of flow measurement and pressure fluctuation.

Asameters model C/G …47 _ 50 all made of stainless steel are designed for applications in potentially explosive areas thanks to their flameproof design,  certified ATEX Ex ia IIC T4, T6… Zone 0 and Zone 1 (on request).

LWQ gas turbine flow meter integrates gas turbine flow sensor and flow converter, its main performance index reaches the international advanced level. It is an ideal instrument for gas metering such as petroleum, chemical industry, electric power, metallurgical industry and civil boiler, as well as for urban gas and gas pressure regulating station metering and gas trade metering.

Asameters model L…38 _ 39 all made of stainless steel are designed for low flow rates with any type of gas or liquid also aggressive, at extreme process and environmental conditions (high pressures and/or low or high temperatures).

LUGB vortex flow meter is a kind of speed flow meter, widely used in petroleum, chemical industry, electric power, light industry, power heating industry. Our company’s vortex flow meter production execution standard is vortex flow sensor (JB/T9249-2015) and verification regulation vortex flow meter (JJG10299-2007).

The Series GFM2 Gas Mass Flow Meter is an ideal choice for the measurement of flow rates of a wide variety of gases. Unit can be calibrated for a variety of gases with user selectable 0 to 5 VDC or 4 to 20 mA and two relay outputs and programmable totalizer that indicates total gas quantity.

LG magnetic flow meter is suitable for conductive medium with conductivity greater than 5μS/cm and with wide nominal diameter range. It is also suitable for various conductive environment conditions where is no pressure loss, with a variety of power supply modes and signal output. It uses standard RS-485 serial communication interface and support international common standards MODBUS-RTU communication protocols, GPRS and other wireless and wired communication networking methods. It can also provide wireless meter reading system (computer management software and database) that can be accessed by remote network.

LBTC positive displacement rotary vane flow meter belongs to volumetric flow meter, which is one of the more accurate instruments in modern industrial liquid measurement.

LGY compact orifice plate flow meter is composed of flow element, differential pressure transmitter, three-way manifold, temperature sensor and pressure sensor, which can measure liquid, gas, vapor and other medium.

Operating principle of LGB Annubar Flow Meter is the same as that of other kinds of differential pressure flow meters, Annubar Flow Meter is superior to other differential pressure flow meters because of its unique structure.
