BQ-PULF Duel Channel Ultrasonic Water Flow Meter The BQ-PULF series single/double channel ultrasonic water meter adopts ultrasonic flow measurement technology, which has a large range ratio, and solves the problem that the traditional water meter idling and small flow rate are not measured. It is widely used in urban water supply pipelines, household water consumption meter, water resource water monitoring, and also applicable to a variety of industrial sites. Ultrasonic water meters use the IP68 solution of the components in the structure, that is, each component is IP68 protection grade. The instrument chamber ensures long-term operation even when it is flooded. What's the main features of Duel Channel Pipe type Ultrasonic Water Flow Meter? 1) Two-channel measurement (DN15 ~ DN40 for single, DN50 ~ DN300 for two channels) 2) 9 digits show cumulative flow, 4 digits on the same screen show instantaneous flow 3) Starting flow rate less than 0.01m/s and accurate measureme

Ultrasonic Level Meter is microprocessor controlled digital level instrument. Ultrasonic pulses generated by the sensor (transducer) sent in the measurement, the surface acoustic wave after reflection by the liquid or receiving the same ultrasonic receiver transducer, a piezoelectric crystal or a magnetostrictive element into an electrical signal by transmitting and receiving sound waves the time between the sensor to calculate the distance to the measured surface of the liquid. As a result of non-contact measurement, the measured media is almost unlimited, and can be widely used for measuring the height of a variety of liquid and solid materials. Technology Features 1) It can be with GPRS and Wifi. 2) Backup and restore settings parameters 3) Measurement of material level, liquid level, volume, weight, etc. 4) Analog output can be adjusted arbitrarily. 5) It has the functions of digital filtering and echo recognition. 6) Can set artificial interfer

BQA100H 0~100Mpa Liquid Gas Oil Pressure sensor BQA100H silicon pressure sensor transmitter is designed for use in applications which deal with corrosive pressure media and require high accuracy. The pressure diaphragm of transmitter is made from silicon material, while its wetted parts are made from 316L stainless steel which possesses a higher degree of resistance against chemical corrosion. The output signals of BQA100H pressure transmitters are configured to meet the need of different controllers used in industrial automation processes, including 4~20mA, 0~5V. With BQA100H one can obtain 0.25 % fs accuracy in measurement with long-term stability. The zero thermal drift is less than 0.04 %fso/°C, while the sensitivity thermal drift is 0.02 %fso/°C over the whole operating temperature range. Email:michael@shboqu.com 2.
