Manufacturers of Rolo Oilfield Wellcheckers.

Rolo Wellcheckers are oil and gas separators with an oil meter and gas meter piped on them to measure well fluid easily and accurately. These units can also be furnished with a free water knockout and with a meter attached to the water discharge line. Wellcheckers are used to make drill stem tests, potential tests, regular periodic production tests, gas-oil ratio tests and marginal well tests. They enable the operator to measure his well production daily to secure accurate records on which to compute royalties and taxes.

Has product images, description, applications and specifications chart to provide product details.
