1. Introduction
HFDPWG type balance measuring station is mainly used for more complex fluid environment and variable fluid medium measurement. HFDPWG balance measuring station adopts the isolation mode of front and rear balance elements in the guide pipe. As the fluid passes through the balancing element, an immediate pressure drop is created downstream. The differential pressure (micro-differential pressure) sensor is used to measure the pressure difference between the upper and the lower reaches of the balance element, and the Bernoulli equation and the law of conservation of energy are used to calculate the media flow data.
HFDPWG type balance measuring station is composed of six parts: balance flow sensor, differential pressure transmitter, flow computer, pressure transmitter, temperature sensor and special instrument box. Compared with the traditional energy meter measurement method,
 
 
2. Technical features:
♦ It can measure mortar, pulp, paper pulp and other difficult materials.
♦ It can measure super high temperature and high pressure steam.
♦ Can measure ultra-low temperature medium, can be used for nuclear experiment, space experiment, ultra-low temperature experiment and so on.
♦ Can measure all kinds of oil, all kinds of chemical liquids, all kinds of gases, mixtures and so on.
♦ It can measure all data in one stop: flow, pressure, temperature, energy and so on.
♦ All data can be transferred in one stop.
♦ It can be measured under bad conditions such as small distance of straight pipe section, valve in front section or multiple curves.
♦ High sensitivity, can measure low flow rate to 0.1m/s, high flow rate to 15m/s.
♦ Stable measurement, long service life, simple installation, free from daily maintenance.
