Its magnet-activated reed switch maintains circuit integrity through dry contact closure, with output transmitted via an integral 12-foot cable. The cable also includes pre-wired leads for tamper detection and common connection, enabling convenient tamper monitoring. The device has passed stringent life and environmental testing, ensuring stable and reliable performance.<\/p>\n<h2>Application Scenarios<\/h2>\n<p class=\"marklang-paragraph\">Ideal for low voltage\/low current applications including:<\/p>\n<ul>\n<li>Transmitting data to \u200c<strong>Automatic Meter Reading\/Advanced Metering Infrastructure (AMR\/AMI)<\/strong>\u200c systems<\/li>\n<li>Sending data to remote totalizers<\/li>\n<li>Flow rate recording<\/li>\n<li>Controlling flow control loops<\/li>\n<\/ul>\n<h2>Compatibility<\/h2>\n<p class=\"marklang-paragraph\">Can be mounted on:<\/p>\n<ul>\n<li>Front-registered diaphragm meters from Elster American Meter, including models AL-175, AT-210, AT-250, AM-250, AC-250, AL-425, AC-630, etc.<\/li>\n<li>ANSI class 250 and ANSI class 400 diaphragm meters manufactured by Invensys\/Equimeter\/Rockwell and Actaris\/Schlumberger\/Sprague<\/li>\n<li>All rotary gas meters from Elster American Meter<\/li>\n<\/ul>\n<h2>Installation Instructions<\/h2>\n<p class=\"marklang-paragraph\">The RVP-FI mounts to the gas meter through the four existing holes normally used to attach the register box. The register and register box are then mounted to the pulser, rather than directly to the gas meter. Driven by an actuator that meshes with the meter&#8217;s register drive, it is compatible with 1\/8\u2033, 21\/64\u2033 and 0.05m\u00b3 drive units. When retrofitting to rotary meters, an additional mounting kit \u200c<strong>#93179K007<\/strong>\u200c is required.<\/p>\n<h2>Technical Specifications<\/h2>\n<div class=\"cosd-markdown-table\">\n<table>\n<thead>\n<tr>\n<th>Parameter<\/th>\n<th>Details<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Model<\/td>\n<td>52870K161<\/td>\n<\/tr>\n<tr>\n<td>Switch Type<\/td>\n<td>1 Form A SPST NO (Normally Open)<\/td>\n<\/tr>\n<tr>\n<td>Pulse Output<\/td>\n<td>1 pulse per revolution<\/td>\n<\/tr>\n<tr>\n<td>Operate Time<\/td>\n<td>0.3 ms<\/td>\n<\/tr>\n<tr>\n<td>Contact Bounce<\/td>\n<td>0.3 ms<\/td>\n<\/tr>\n<tr>\n<td>Initial Contact Resistance<\/td>\n<td>100\u03a9<\/td>\n<\/tr>\n<tr>\n<td>Maximum Operating Voltage<\/td>\n<td>24 VAC \/ 24 VDC<\/td>\n<\/tr>\n<tr>\n<td>Maximum Operating Current<\/td>\n<td>100 mA<\/td>\n<\/tr>\n<tr>\n<td>Power Supply<\/td>\n<td>External<\/td>\n<\/tr>\n<tr>\n<td>Operating Temperature<\/td>\n<td>-40\u00b0C to +70\u00b0C<br \/>\n<em>Note: Always verify the operating temperature range of the gas meter, which may be more restrictive<\/em><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h2>Ordering Information<\/h2>\n<p class=\"marklang-paragraph\">The RVP-FI can be installed directly on new gas meters, or ordered separately as a retrofit kit.
