Primarily designed for low flow applications where high accuracy performance is required, the HPC Coriolis flowmeter covers three basic measuring ranges: 0-20kg/h, 0-50kg/h, and 0-160 kg/h. Volume flow rates can also be calculated via the transmitter.
The "Dual Bent Measuring Pipe" concept and the extremely compact dimensions are the heart of the HPC product range. Heinrichs’s reputation for quality and robust construction are renowned, and the new HPC is no exception with stainless steel 1.4561 (316 TI) measuring pipes, stainless steel 1.4404 (316 L) flow body, and a combination of stainless steel and anodised aluminium enclosure covers.
Due to the compact design of the HPC, the pairing of a remote mounting transmitter is required. The integrated electrical plug concept allows for an uncomplicated cable connection to the Heinrichs UMC-4 remote mount transmitter, providing multiple output options, including HART® communication, and with ATEX/IEC-Ex certification.
Why a dual bent measuring tube design ?
For low flow with high accuracy and reliability, single tube Coriolis flowmeters are compromised.
For the measurement of very small flow rates, it is common practice for manufacturers to use single pipe Coriolis designs, however, with the use of just one measuring pipe the influence of external interferences increases dramatically, often necessitating a costly decoupling. Also, with low-flow Coriolis sensors, the weight influence of the sensor coils due to the mechanical measurement principle is significant when compared to the weight of the measuring pipes, thus, the relation of the pipe diameter to the weight of the sensor coils primarily defines the limits of the construction principle for small pipe diameters.
As the first manufacturer worldwide, Heinrichs have overcome the limitations of single pipe Coriolis flowmeters by providing a Coriolis sensor concept with dual bent measuring tube design and sensor coils mounted between, rather than on the pipes, and lightweight magnets mounted onto the pipes. This provides the sensor with a significantly noise-reduced and predictable dynamic behaviour, capable of working at higher frequencies, so further decoupling the sensors measurement from external vibrations. Furthermore, up to 4 sensor coils are positioned between the pipes, increasing the resolution accordingly. With these characteristics, the new HPC Coriolis Sensor is therefore not only extremely accurate, but also particularly resistant against external interferences.
