Description
Honeywell offers 8-inch and 12-inch meter-driven chart recorders for installation on large volume diaphragm, rotary and turbine meters.
The major feature of these recorders is the volume oriented chart. Volume recorders are available with wall, flush, portable or pipestand mounting.
Each element deflects 22 1/2 degrees for the design range, is carefully made, heat-treated and cold-worked to remove all hysteresis.
The accuracy of each pressure recorder is +/-1/2 chart graduation.
What Is It?
The 800 and 700 series volume recorders from Mercury Instruments utilize the 8” circular volume chart, while the 1200 and 900 series recorders use the 12” circular volume chart. Meter driven charts can be processed on an electronic optical scanner, if they are printed in scanner blue, and pressure and temperature lines do not cross one another on the chart.
How Does It Work?
The output wriggler of the meter provides the mechanical force to drive the gear train in the recorder through the universal mounting bracket. The output shaft of the gear train rotates the circular volume chart. Since the meter drives the circular chart through the gear train, the amount of chart rotation represents the amount of volume passed through the meter. Meter driven charts are divided into 100 equal segments.
What Problems Does It Solve?
Volume Recorders from Honeywell provide volume measurement in areas where power is scarce for temporary or permanent applications.
FeaturesThe valve and test fitting is provided with each pressure element. Solid door, tamper-proof case, and double-latch bar with padlock-type handle are also provided (811-S and 812-S have clasp closure for the padlock).
- 800 series recorders use an 8-inch diameter chart, 6 3/8" arch radius.
- 700 series recorders use 12-inch diameter chart, 9 7/16" arc radius single-pen, or, in some models, the 8-inch chart, 6 3/8" arc radius two-pen.
- 1200 series recorders use 12-inch Mi chart, 6 3/8" arc radius.
