Planning for the BI-1000 Gas Mass Flow Meter

The BI-1000 Gas Mass Flow Meter is designed to accurately measure a gas flow rate, compensated for temperature and pressure to standard conditions and totalize the compensated volume of gas flow. By choosing the appropriate model from a selection of more than 90 available flow rates, flows can be accurately measured from 2 sccm up to 1500 SLPM. The totalizer can be started by the user at any point and will accumulate flow until reset.

Choosing Your Flow Rate

When choosing the flow rate of the BI-1000 that you will purchase, you should determine the maximum flow rate to be measured. The BI-1000 has more than 90 available flow rates. The Meter will be scaled for you so that the analog output will show the maximum flow rate at 20 mA or 5 volts depending on your selection. Go To Flow Rate Selection Page

Choosing Your Optional Laminar Flow Element Re-Ranging Kit

If you purchase the optional re-ranging kit, you can quickly, easily and economically extend the range of your BI-1000 Flow Meter. The re-ranging kit consists of three laminar flow elements chosen from the wide selection of more than 90 available, along with instructions, removal and installation tools and pre-loaded software which you can quickly access on the menu screen. Re-ranging takes about 15 minutes depending on your installation. Go To Re-ranging Page

Choosing Your Optional Fluid Connectors

The BI-1000 Meter will have 3/8” NPT internal threads for all flow rates. The optional fluid connector kit includes polypropylene fittings and tubing. The kit includes fittings and tubing for 3/8” and 1/4”. Two of each connector and 10 feet of each size of tubing are included with each kit.

Choosing Your Optional Power and I/O Cables

The BI-1000 Meter comes with a standard BI-1000 Meter I/O cable which includes a 110 volt, 60 Hz ungrounded wall adapter with an output to the Meter of 15 volts DC and flying leads for one analog output and static ground. If your installation has a power source different from the above, if you need to access more of the available I/O, or if you need a custom plug attached to your cable, you can choose from our wide selection of optional.

Ordering the BI-1000 Gas Mass Flow Meter

Follow these steps to choose a complete BI-1000 Meter package:

1. Choose your flow rate from one of the three groups (click on the Flow Rate Selection button at the left to view the complete list of flow rates within the group).

a. Low Flow Group – 30 different flow rate selections from 2 sccm to 2 SLPM

b. Middle Flow Group – 80 different flow selections from 2 SLPM to 400 SLPM

c. High Flow Group – 10 different flow selections from 400 SLPM to 1500 SLPM

2. Choose an optional Re-Ranging Kit by picking three additional flow rates within the same group as your primary flow rate.

3. Choose an optional Fluid Connector Kit which matches the NPT size of the range that you have chosen.

4. Choose an optional Power and I/O Cable from the list of available cables for the BI-1000 Meter.

5. Make a list of your specific System Application Conditions (see Forms) so that your Bowman customer service representative can better assist you to ensure that your Meter will be right for the application.

6. Call your Bowman customer service representative and place your order.
