Double-flange differential pressure transmitter
Thread Content
When is a dual-flange single-capillary differential pressure level gauge used? When to use double flange double capillary? Does the difference in length between the high-voltage and low-voltage sides affect the measurement?
The choice of when to use double flanges depends on the parameters of the process medium. It does not affect measurements if the double-flange capillaries are of different lengths; the question is, are there double flanges with positive and negative pressures of different lengths? Haven’t seen it before really
Do you mean the difference between a single-capillary and a dual-capillary transmitter? A single capillary is essentially a pressure transmitter. Transmitters with flanged capillaries are generally used in conditions such as corrosion, high viscosity, or when the pressure measurement point is too high to facilitate maintenance.
A single tube is used to measure the liquid level in open containers, while a double tube is used to measure the liquid level in closed containers
Double flanges are used for sealed tanks; the height or length doesn’t really matter. For example, with a 10M tank, if you install them in the middle, it will be inconvenient for maintenance
Yes, our unit currently has ones in use – short for positive pressure and long for negative pressure
