Local Display Units with Frequency and Analogue Output (VTM)
Local display unit swith frequency and analogue output, optionally with stainless steel housing, e.g. for off shore and chemical injection applications.
Specifications:
- LCD display: 8 digits (14 segments), digit height 7 mm for real-time value, totals and programming, slewable in steps of 90° after losening the fixing screws
- linearization: possible with 10 points
- ambient temperature: –40 up to +70°C
- fluid temperature: –40 up to +120°C
- Ex-protection: EX II 2 G EEx ia IIC T4
The VTM is a programmable local display with integral carrier-frequency pickup and amplifier. It serves the evaluation of flow volumes. Measuring results are indicated in an 8 digit LCD display with 14 segments. A 10 point linearization is included to optimize the accuracy.
The pulse output provides a flow-proportional frequency signal or scaled volume pulse in accordance with programming. The measuring signal may also be scaled in a 4–20 mA current loop.
