Units are equipped with a standard 6-turn needle valve for flow rate control. High precision metering valves with non-rising stems (sold separately) are available for high sensitivity control and resolution – particularly suited for very low flow rates.

The Series DR Direct Read Variable Area Glass Flowmeters are ideal for the direct flow measurement of air, water, and other commonly used gases. These flowmeters are designed with direct read scales with no need for correlation charts. They feature borosilicate glass tubes in 150 mm or 65 mm scales with aluminum and SS metering valve options.

Customize flow systems to meet application requirements. Systems can be configured with up to six different flow tubes with various flow capacities and flow patterns. The Series MTF Multitube Flow Systems are ideal for multichannel metering, mixing, or monitoring applications.

The Compact Series OMA Oxygen Flowmeter is made especially for medical applications and manually controlling flow from oxygen generators. Flow levels are kept stable by precision valve and knob adjustment. The low cost flowmeter is made from durable clear acrylic plastic. They easy-to-read scale is hot stamped into the acrylic so it will not wear off. The ball float is highly visible against the light blue background. Readings are repeatable within ±4% full scale accuracy.

Orifice Asameters D6, also called kinetics, have measuring tube separeted from the main orifice and are ideal for remote installation, when the metering point is not the same of that of reading.

These Asameters® are a sight flow indicators of liquids in pipelines at any angle and direction of flow.

Orifice Asameters S6, also called kinetics, have measuring tube in shockproof plastic and are suitable for the measurement of high flow rates of aggressive fluids (acids and alkali) directly on the pipeline thanks to the metering tube connected with the main orifice plate.

MTF variable area flow meter for micro flow can measure tiny liquid or gas, which has the characteristics of stable and reliable measurement and wide application range. The instrument is equipped with a fine-tuning valve to facilitate the user’s setting of a specific flow rate. Instrument is based on the float measurement principle. According to the flow direction of the medium, it can be divided into side in and out, bottom in and out of two types. According to the display mode, it is divided into mechanical pointer type and liquid crystal display with 4-20 mA current output type.

Orifice Asameters Z6, also said kinetic Z6, have the measuring tube directly connected to the main flange, therefore the reading is made directly on the pipeline. They are suitable for the measurement of large flow of water or clear liquids and have reading scales largely increased compared to conventional flow rate range of orifice Asameters series D6-S6-U6.

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.

Vortex flowmeter has no moving parts, simple layout of measuring elements, reliable function and long service life. The volume flow of the vortex flowmeter is not affected by thermal parameters such as temperature, pressure, density or viscosity of the fluid being measured. It usually does not need to be calibrated on its own. It can measure the flow of liquid, gas or steam. The resulting pressure loss is small. In addition, the vortex flowmeter has the advantage of high accuracy.

Asameters® model V6, proprietary, are flap type flow meters with flow rate reading by pointer, output signal 4-20 mA and HART-Protocol (power supply: 24Vdc ± 10%).

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.

This new model, at high performance solutions, both as hardware and software, can be defined as an HI-TEC line, addressed to very demanding customers from the point of view of performance and precision.

Output signal is both analogical and digital; and qualitatively the instrument is very performing, having accuracy <+-0,5% of reading and repeatability of 0,1% r.v.

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.

LUGB vortex flow meter is a kind of speed flow meter, widely used in petroleum, chemical industry, electric power, light industry, power heating industry.

Flanged sensor has a rugged and reliable build. All of its internal components and wiring are isolated from environmental hazards, even the toughest, because the measuring tube in stainless steel 304 and the outer tube in carbon steel are welded to provide a hermetic seal. Therefore it’s free from long-term maintenance.
Easy and fast to install and start up.

Flow element, also known as differential pressure flow meter, consists of a primary detection piece (flow element) and a secondary device (differential pressure transmitter and flow indicator). Flow element is the most stable and reliable of all flow meters, which has a history of more than 100 years. Its wide applicability, high reliability and accurate accuracy make it widely used in the measurement of gas, liquid and vapor.

Wafer sensor has a rugged and reliable build. All of its internal components and wiring are isolated from environmental hazards, even the toughest, because the measuring tube and the outer tube both in stainless steel are welded together to provide a hermetic seal. Therefore it’s maintenance free and provide a long-term reliability. Easy and fast to install and start up.
