2.1 DESCRIPTION The HMP is a volumetric turbine flowmeter. As liquid flows through the meter, it causes the rotor to spin. An external non-contact pick-up probe counts each passing vane of the rotor as it spins. Each revolution of the rotor equates to an exact volume of liquid.
NOTE: If it becomes necessary to splice cable connections, be sure to properly solder or join wire connections. Loose connections have the ability to generate false counts.

This identifies the amount of pulses the meter will output per a fixed volume that passes through it. In the case of Anderson flow products a gallon is the volume. This value is labeled on the meter body as a “P/G” pulses per gallon, which is also know as a “K-Factor”.
Section 6 - Maintenance The HMP flowmeter, if properly applied, should provide many years of trouble-free service. Excessive flow rates and/or temperature and pressure are conditions which most commonly cause damage to the flowmeter. 6.1 DISASSEMBLY AND INSPECTION Verify that all line pressure is relieved with all valves closed prior to removal of the meter. Disconnect signal cable and completely remove meter body from the product line.
6.3 ASSEMBLY Verify the rotor spins freely on the shaft prior to installation. Rotate parts until they fall into place. Match assembly pieces with the orientation shown. (Figure 6.2) DO NOT FORCE THE PIECES TOGETHER! Be sure the gasket between the meter housings is in the groove of the body connection area. Secure the housing clamp and reinstall in the process line.
