Installation Procedure—Direct Mount to a Turbine Meter (CSA Compliant)

A Scanner 2000 without the MVT bottomworks can be mounted directly to a gas turbine meter for measuring

natural gas. A pipe adapter and union are attached to the Scanner, allowing a direct connection to the turbine

meter.

WARNING HAZARDOUS AREA USE. The Scanner 2000 is certied for hazardous area use only when

installed in accordance with applicable standards and local wiring practices. Carefully

review Hazardous Area Installations, page 27, to determine specic installation require-

ments (cable glands, conduit seals, signal cable, RTD, etc.).

An external pressure transducer is required for converting the pressure to a 4-20 mA or 1-5V signal, and the

Scanner 2000 must be equipped with the optional expansion board, which provides the analog input necessary

to receive the pressure signal from the transducer. If installed in a Div. 1 hazardous area, the transducer must

be explosion-proof.

Figure 2.8—Direct-mount installation for use with a gas turbine meter

To connect the Scanner 2000 to a turbine meter using this method, perform the following steps:

1. Position the Scanner 2000 above the gas turbine owmeter.

2. Plug the Scanner 2000 cable connector into the magnetic pickup of the turbine meter and hand-tighten the

knurled nut on the connector.

3. Screw the Scanner 2000 onto the owmeter threads surrounding the magnetic pickup with the display fac-

ing the desired direction.

CAUTION Do not use Teon

tape on the threads of the union, adapter, or pipe plugs. Use of

Teon

tape will void the explosion-proof rating of the instrument.
