Temperature and pressure compensation vortex flowmeter
Description of temperature and pressure compensation vortex flowmeter:
LUCB type vortex flowmeter sensors, which can be widely applicable to all kinds of industry of large diameter gas, liquid and steam flow measurement, also can measure the turbid liquid containing small particles, impurities, and can be used as flow transmitter used in automatic control system.
Features of intelligent one-piece vortex flowmeter :
1. No depletion disassembling sensors can be realized, which can realize the amplifier and sensor separation (15 m) separation distance
2. The interference elimination circuit and anti vibration sensing head, make the instrument has certain environmental vibration resistance
3. Pressure loss is small, the span a wide range, range of up to 25
4. Have no moving parts, long-term stability, the structure is simple and easy to install and maintain
5. Measurable medium temperature up to + 250 ℃.
