Manufacturer:
Endress+Hauser
Product Name:
Deltabar FMD 71/72
Product Description:
Level Transmitter
Profile:
HART Field Device
More Information:
Electronic differential pressure for level measurement Differential
pressure transmitter with metal sensors Overload-resistant and
function-monitored.
Application
The Deltabar FMD72 is used to measure the level, volume or mass of
liquids in pressurized tanks. The system compromises two sensor modules
and one transmitter. One sensor module measures the hydrostatic pressure
(high pressure) and the other one the head pressure (low pressure). The
level (electronic differential pressure) is calculated in the transmitter
using these two digital values.
Your benefits
The electronic differential pressure measurement system eliminates issues
of traditional differential pressure measurements using impulse lines or
capillaries:
* Eliminate measurement drift due to ambient temperature changes
* Eliminate line condensation or evaporation events (dry/wet leg
inconsistencies) and plugging events
* No high cost of heating impulse lines to prevent freezing
(installation, energy)
* Eliminate tubing and connection leaks often seen with traditional
systems
* Multivariable level measurement: HART-based differential pressure,
head pressure and sensor temperatures from one system
* Continuous health indication of the entire system via HART-based
diagnostic
* Intuitive menu-driven installation
* Color-coded wiring
* High reproducibility and long-term stability
* High reference accuracy of individual sensors: up to ±0.075 %, as
PLATINUM version: ±0.05 %
* Increased process availability and reliability
* Safety risks are minimized with the new electronic differential
pressure system architecture and design
* Lowest total cost of owner ship due to reduced installation time,
maintenance downtime and spare requirements.
