Kofloc Low–Cost Mass Flow Meter With Display Model 3810DS II Series

Low–cost Mass Flow Meter With Display

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 flow
sensor and precision needle valve built into one piece.

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 tem-perature and pressure.

relating to the flow range (e.g., flow range, accuracy and
repeat-ability) 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 atmos-phere. For details on the pressure requirements,
ask us.
