Inline flow meters are the main structure of flow measurement device. Water meters and most of flow meters usually adopt such design. In order to meet different requirement, we also offer ultrasonic inline flow meters with very competitive price. With our patented DSP technology, our inline flow meters can reach the accuracy of 0.5%.

Our inline flow meters have separated type and integrated type. Separated type refers to the electronic converter and flow transducers are two single parts and connected by cable. Users need to confirm cable length while order. The default is 5meters. Integrated type are a whole body.Electronic converter and flow transducers are welded together.

Inline ultrasonic flow meters are digital electronic flow device and it has versatile outputs of 4-20mA, OCT pulse, relay, RS485,Modbus,M-Bus. If select separated type, big memory data storing is optional. The inline meters can bear max 150 Deg.C and the default water-proof class is IP65, and high class IP68 can be made as requirement.

Maybe you are puzzled why ABEST still manufacturers inline ultrasonic flow meters since we have clamp on and inline type. That's because it is from the actual requirement of market and customers. The following are comparing with mechanical flow meters(e.g. turbine,etc) and electromagnetic flow meters.

1.Comparing with Mechanical Flow Meters

Mechanical flow meters usually utilize moving parts to sense fluid. The moving parts will be damaged after several time using,especially the water quality is poor or have dirty thing in fluid. Our inline ultrasonic flow meter has no moving parts and can easily avoid these problems.Meanwhile,its accuracy is not degraded as its using. Also, we can make our price not higher than mechanical flow meters,e.g.turbine flow meters. Thus, when you select flow measurement, it is advisable to select our ultrasonic inline flow meters.

2.Comparing with Magnetic Flow Meters,

In the market, magnetic flow meters will be the main competitor of inline ultrasonic flow meters. But our inline flow meter has a higher cost-effective solution for 0.5% accuracy. Meanwhile, several liquids with low conductivity is not suitable for magnetic meter. These liquids mainly have ultra-pure water, fuel,etc. However, ultrasonic flow meters will have a good performance.
