features
High linearity and good repeatability
Because the HJP series porous balance flow sensor has the characteristics of porous symmetrical structure and a large number of test data show that the porous balance flow sensor can balance the flow field, reduce the eddy current, reduce the vibration and signal noise, greatly improve the stability of the flow field, and make the linearity It is 5~10 times higher than the orifice plate, and the repeatability is increased by 54% to 0.15%. From the perspective of its comprehensive performance, the porous orifice flowmeter has high-end flowmeter performance and can be used for trade measurement.

HXUR series liquid level transmitters are divided into two types: HXURK and HXURT. HXURK uses the famous American NovaSensor company's high-precision and high-stability diffused silicon pressure sensor components. HXURT chooses the dry ceramic capacitive sensor of E+H company. The high-quality sensors, exquisite sealing technology, and perfect assembly process of the two liquid-level transmitters ensure the excellent quality and best performance of the product. The two types of liquid-level transmitters are divided into two types of medium measurement: cable type and armored type. The armored type can resist the erosion of various corrosive liquids and can meet the needs of customers to the greatest extent.
