Low–cost Mass Flow Meter With Display
MODEL 3810DS II SERIES
The Model 3810DS II is a mass flow meter with a built-in display using a time-tested flow sensor. The 3810DS II displays total flow in addition to instantaneous flow, which is an improvement on the previous model 3810DS. Just like the 3810DS, the 3810DS II is also available with a flow sensor and precision needle valve built into one piece.
Features
- Precision needle valve for controlling and monitoring very low flow rates
- Two-alarm outputs for flow monitoring
- Analog output for instantaneous flow and pulse output for total flow
- Compact and lightweight
- The display is built-in and the meter only requires connection to a 24-VDC power supply.
- The meter measures mass flow and directly reads the flow.
- There is no need for flow correction calculations based on temperature and pressure.

!!NOTE!!
Specifications
relating to the flow range (e.g., flow range, accuracy, and
repeatability) are expressed in N2 or air equivalent. The product will
be built with the primary pressure of 300 kPa or less and the secondary
side open to the atmosphere. For details on the pressure requirements,
ask us.
