CTR
Counter (CTR)
An 8 digit non-compensated index registers displaced volume in Actual Cubic Feet (ACF) or in Actual Cubic Meters (m³).
TC
Temperature Compensated (TC)
Temperature compensation, available in meter sizes 8C-16M, is accomplished by a mechanical computer with a spiral bi-metallic thermocouple (probe) located in a sealed temperature well at the meter inlet. Series 3 TC Units provide corrected gas volume readings to a 60ºF (15ºC) base temperature for readout in Standard Cubic Feet (SCF) or Normal meters Cubed (Nm3) between flowing temperatures of -20ºF and +120ºF (-29ºC and + 49ºC).
CD/TD
Counter or Temperature Compensated with
Instrument Drive (CD/TD) The Universal Instrument Drive (ID) Assembly adapts to the CTR and TC Accessory for installation of a corrector, chart recorder, or other externally mounted, mechanically driven device. The ID Assembly is mechanically linked to the CTR/TC mechanical gear reduction unit. One revolution of the instrument drive dog represents a specific displaced volume measured by the meter.
Solid State Pulser
Solid State Pulser
The ROOTS® solid state pulser generates low frequency pulses representing volumetric information for remote reading. Mechanical switches have been eliminated for maximum reliability. No battery or maintenance is required. The electronic circuitry is enclosed within the same cover that houses the mechanical gear reduction unit. Brochure
ICEX
ICEX
The ROOTS® CEX counter with electronic transmitter is a single channel, transistor output device that provides a non-compensated, high frequency pulse output (four pulses per impeller shaft revolution) for applications requiring gas flow rate and totalization information. Brochure
Series 3A
Roots® Series 3A Accessory Units for LMMA Meters
Dresser’s new S3A Accessory unit - that mounts to your LMMA meter - features the same high quality and long-term reliability of the oil-free S3 Accessory unit.
Dresser’s new residential AMR Adapter for the Series 3 ROOTS CTR/TC and the Series A (LMMA) CTR/TC accessory units allows you to mount an Itron® Residential ERT® 40G for Invensys or American Meters directly onto a Dresser ROOTS Series B3 or Series A Rotary Meter. Additionally, there is an Adapter to mount an American footprint Cellnet Module directly to the end of a ROOTS® Rotary Meter.
