Permanent Ultrasonic Clamp on Flow Meter

The permanent ultrasonic clamp on flow meter has been manufactured with patent digital signal processing techniquies and is equipped with many powerful functions.The clamp on flow meter has been developed to several generation. Comparing with previous version,the latest version becomes more advanced and has much more function.

The clamp on flow meter can provide non-invasive flow measurement for clean liquid in closed pipe. Depending on  different size of clamp on transducers,the flowmeter has wide measurement range for pipe size. It can work on metal and plastic pipes, typically  including carbon steel, metal steel, PVC, PE,copper, etc. Due to non-invasive installing way, ultrasonic clamp on flow meter doesn’t need to cut pipe,thus it is featured with  no moving parts,no pressure loss,no maintenace cost,no risk of leakage,etc.

The permanent clamp on flow meter is wall-mount fixing installation and its metal enclosure can reach IP65 class.  The clamp on flow transducers are also IP65 class. After filling with glue, the tranducers can reach IP68 class  and can work in water.  The clamp on transducers have no limiting for working pressure. Only pipe can bear the big working pressure, the clamp on transducers can work normally.

Except clamp on flow transducers,the  ultrasonic flow meter can also support insertion transducers and inline transducers. For insertion transducers, its Min pipe size should be over DN65mm or DN50mm.We also develop patent hot-tap installing tool for insertion transducers. With the special tool, users can install insertion transducer without flow stop under pressuer of 0.8MPa.

The clamp on flow meter also has versatile outputs and communication protocol. The flow meter has outputs of 4-20mA, OCT pulse output, frequency output, relay output and RS485 port which can support Modbus,M-bus and factory’s communicaiton protocol.

The ultrasonic clamp on flow meter can be functioned as ultrasonic heat meter after being equipped with PT100 resistor. The PT100 resistors can be insertion type or clamp-on type. For each set of ultrasonic heat meter, the PT100 resistors should be pair(2pcs) and in order to ensure good accuracy, each pair of PT100 should be carefully calibrated.
