Similar to the Basic, the Bi-Directional VA Meter offers a low-cost alternative to other flow meters, but is uniquely suited to systems where the flow direction changes. Ports are available in brass, aluminum, and stainless steel to meet system and fluid requirements. The rugged, weather-proof design allows for outdoor installation and wash-downs, unrestricted mounting (horizontal, vertical, and inverted), as well as years of maintenance-free performance. The meter allows for operation up to 6,000 psi, and is offered in NPT, SAE, and BSPP ports, eliminating the need for adapters.
